Melbourne Heart brimming with confidence after encouraging performances against Victory, Mariners Melbourne Heart V Central Coast Mariners match review. GOLGOL Mebrahtu says encouraging performances against A-League title favourites Melbourne Victory and Central Coast has given Melbourne Heart players renewed confidence with which to attack this season. Heart drew 2-2 with Central Coast at AAMI Park on Saturday. A brace from David Williams early in the second half had John Aloisi's men on track to register their first win of the campaign before two contentious penalties were awarded to the Mariners - both of which were converted by Marcos Flores. Mebrahtu said the penalties were something "you can't help and hopefully that evens itself out over the course of the season," but said there was a positive vibe among the players after the first two rounds. "We're not stopping here, we know we can improve as well," Mebrahtu said. Confidence is high at the Heart after positive performances against the Victory and Mariners. Picture: Mark Nolan. But you saw what Victory did to Adelaide in the second half on Friday night and with the Mariners we're talking about the defending champions and against those two good teams we've held our own. We were very unlucky to have not won yesterday (Saturday) and in the first game we probably had the better of the chances, so we're doing really well, we've started the season well and hopefully we can keep improving. Heart looked dangerous in attack on Saturday and that was without captain Harry Kewell and Maltese international striker Michael Mifsud. Both Kewell (neck injury) and Mifsud (international duty) are expected to return for next Sunday's game against Perth at nib Stadium, creating a selection headache for Aloisi. Mebrahtu said it was heartening to be able to create so many chances against the Mariners even with Kewell and Mifsud sidelined. "We could have easily won that game 4-2, 5-2 with the opportunities that we had," Mebrahtu said. Everybody knows the abilities of Harry and Michael, they're both very experienced players and having them in our side will boost us even more. But across the season things can happen - injuries, suspension, whatever - and we know that we have the depth in our squad to cover and perform well to get the results. Heart is yet to concede a goal from open play this season, a fact Mebrahtu said gave he and his fellow forwards enormous confidence when in attack. "You're talking about two very classy players in Patty (Kisnorbo) and Rob (Wielaert) - and even Patrick Gerhardt is there too but unfortunately only two centre backs can play a game," he said. It's good to know that we're defensively (sound) and it's not just with those two, it starts from the front line. When we defend as a team our structure is good and that only makes things easier. When you don't concede you only need one goal to win.
