Round seven features a mouth-watering top-of-the-table clash: Brisbane and Western Sydney Football correspondent Richard Bayliss sits down with Alessandro Del Piero to talk about his life in Australia and his new book 'Playing On'. Is this mob the biggest challengers to the Wanderers? THE A-League's oldest grudge match is sure to light up a bumper round seven, but it kicks off with arguably the match of the season so far on Friday night. Brisbane Roar v Western Sydney Wanderers, Suncorp Stadium, Friday 8pm (EDT), Fox Sports 1 HD Head-to-head: Western Sydney 4, Brisbane 0 He's back. Besart Berisha returns to the Roar line-up in time for this heavyweight match-up between teams one and two and if Tony Popovic's side were looking for a test to gauge their undefeated start to the year, they'll get it in Brisbane. Mike Mulvey has been resourceful over the past couple of weeks, getting plenty out of the likes of Dimitri Petratos, Diogo Ferreira and James Donachie. But Berisha joins Matt McKay and Ivan Franjic as big 'ins' at Suncorp on Friday night. But they're up against a real nemesis. Wanderers scored their first ever goal at Suncorp, haven't lost to the Queensland outfit and have only conceded once against them. This time around, Mulvey's side are in great shape. They're just as stingy as the Wanderers defensively, and it shouldn't come as a surprise with the energy and pack mentality they defend with. But the fascinating match-up comes tactically. Roar have completed the most passes in the league (3451) this season at the second best pass accuracy (82.6%) and have averaged 58 per cent possession of the ball all season with their 'pass and move' philosophy. Meanwhile, Popovic's side have the lowest percentage of backward passes league this season - they're always looking to break, at speed, and with deadly precision when they disrupt their opponents' attack. It will be intriguing to see two relentless units go at each other in a match that should be of finals quality. "The return of (Franjic and McKay) should get Brisbane Roar across the line on Sunday night," Andy Harper says. Sydney FC v Wellington Phoenix, Allianz Stadium, Saturday 5.30pm (EDT), Fox Sports 1 HD Head-to-head: Played: 20 Sydney FC 10, Wellington 9, Drawn 1 Sydney FC have won their last two and will be looking to make it three as they host Wellington on Saturday. Well, well, well. Should Sydney win at home to Wellington on Saturday afternoon, they will be entrenched in the top six, with three wins on the bounce, and all of a sudden it's sunny over Allianz Stadium for Frank Farina. The last time these two met, Alessandro Del Piero provided a football masterclass in a 7-1 drubbing and the last thing Phoenix's All White contingent will want is another thrashing after their tough week at the hands of the Mexicans. The last time the Sky Blues notched three straight wins within the same season was 2007-2008; this sort of consistency has been a long time coming for a club with so many false dawns, but there's still a lot of improvement needed. Frank Farina says his side know a run of home games off the back of consecutive wins provides a great chance to emerge from the log-jam in the middle of the ladder. Farina's side are only hitting the target with 34.6 per cent of their efforts on goal, they're winning less than half the aerial contests defensively and are still the second worst team in the league in terms of discipline. The more stability Farina can get in his line-ups, the more likely we'll see Sydney less reliant on speculation from long range, and more clear-cut chances crafted in the area. Melbourne Victory v Adelaide United, Etihad Stadium, Saturday 7.30pm (EDT), Fox Sports 1 HD Head-to-head: Victory 15, Adelaide 10, drawn 6 In the latest instalment of the A-League's original grudge match, both teams go to Etihad Stadium looking to turn their good on-field form into points. Josep Gombau and Kevin Muscat have both watched their teams play good football but come away frustrated. Gombau's Adelaide are clearly still a work in progress, while Muscat has maintained the style, if not the results, of Ange Postecoglou at Victory. A win against the Reds would be just the sort of result Muscat would like to get his senior coaching career of the ground. Andy Harper says: "Adelaide are a team that has been promising a lot. They've had some good performances without winning and more losses than they would have liked. The challenge for Adelaide is to stick together and believe in what they're doing because I don't think they're too far off. They've had a pretty impressive start to the campaign and they just haven't got the points to match the on-field they've got to turn that around, they can't afford another week or two of leaking points because teams will get too far away from them. The stats back up Harps's analysis. The Reds have had more possession than their opposition in all six of their matches this season. But they haven't won in five games, with a lack of concentration in defence costing goals. Six of the nine goals Gombau's side have conceded this season have come in the second half. They have conceded three times from headers and three from corners, two of which came from failed clearances. History is on Victory's side. Their 15 wins against Adelaide are the most against any opponent; however they have only won one of the last nine games against the Reds. Adelaide have won just once at Etihad, losing 10. Postecoglou's legacy is clear: Victory lead the league in total shots (13.8), shots inside the box (8.5), corners (6.8) and balls in the penalty area (31) per game, and only Brisbane have scored more than Victory so far this season. Kevin Muscat's priority must be the defence, in particular stopping his side going behind early, shipping six of their eight conceded in the first 45 minutes. Only Sydney FC have conceded more first-half goals. Perth Glory v Central Coast Mariners, nib Stadium, Saturday 9.30pm (EDT), Fox Sports 1 HD Head-to-head: 25 Central Coast 15, Perth 4, drawn 6 Central Coast face the arduous trip to Perth for their first game without title-winning coach Graham Arnold. Former No. 2 Phil Moss steps up to the big chair with a fine inheritance but big shoes to fill. And the champions haven't quite looked like their old selves so far this term. Just one win in five (their worst start since season 2008/09) and six goals conceded suggests Moss has some work to restore the Mariners to their previous best. The 0-1 loss to Brisbane in their last match was the first time that the Mariners have failed to score in their past 10 matches, and only three of their goals have come from open play, with the three others from penalties. Central Coast prepare to battle Perth at NIB Stadium in their first game under new coach Phil Moss. Their away form hasn't been convincing either, with four goals conceded in two 2-all draws - although given they've come from behind both times, don't write them off just yet. Glory have enjoyed a similarly solid if not winning start to the season, winning two, drawing three and losing just once. After that opening-day loss to Adelaide where they conceded three times, Perth's defence has looked pretty tight, conceding just twice in the following five games. Alistair Edwards's side walked away with a point against Adelaide in scorching conditions that the said impacted their game. With a later kick-off making life easier, they'll be hoping to improve on a poor record against the Mariners, having won just four matches in 25 meetings - but all of those have come at home. Marquee signing William Gallas could make his first start after coming off the bench last weekend while Shane Smeltz returns from international duty. The Kiwi striker's return could be key as scoring looks to be an issue for Glory at the moment; they are yet to score multiple goals in a game this season, although they have only failed to score once. Perth have struggled to create attacking opportunities, taking the third fewest shots (11 per game) and have the second fewest shots on target this season (3.8 per game). Newcastle Jets v Melbourne Heart, Hunter Stadium, Sunday 5pm (EDT), Fox Sports 1 HD Head-to-head: Jets 4, Heart 3, drawn 2 Newcastle host a Melbourne Heart side looking to get off the bottom of the ladder. How quickly your fate can change in football. A couple of weeks ago it was Gary van Egmond who was sweating. Two wins later - including that impressive come-from-behind victory against Brisbane - and Dutchy can hand that slightly stale smelling towel to John Aloisi. Bottom of the ladder, no wins, four consecutive losses - it's a credit to Aloisi's personal sense of style that he doesn't look as bedraggled as his football team. But the pressure must be starting to tell. Not the ideal time to travel to a Jets side with rising confidence and lacking the still not fit Harry Kewell. Andy Harper says: "The Jets come after two successive wins after a poor start to the season. They're starting to look convincing as a football team; settled selections and young players who are playing with real verve at the moment. Heart are bereft of confidence, the goal drought has to stop - but more importantly they have to focus on protecting their own goal, I think that where they've let this whole momentum slide. The return of Patrick Kisnorbo will plug up the back and the gaps and defence. The stats make horrible reading for Heart fans: winless in their past 11 matches, they have been outscored a frankly ridiculous 19-4 during this stretch and are just the second team to have less than two points in six rounds in A-League history. They have scored a league-low of two goals in six and average a league-low 2.7 shots on target per game. We really could go on and on - but you get the picture. Considering the Jets are unbeaten at home this season, John Aloisi's men will have to dig very deep to get something from this game. The comeback has to start somewhere - or the coach could find himself somewhere else.
