Key members of the Socceroos set to gain valuable playing time in key relegation/promotion battles Mile Jedinak (top) and Crystal Palace are set to meet Watford in a play-off game. THE Socceroos' World Cup fate is on the line next month and what better way to prepare than playing do-or-die clashes? A chunk of Holger Osieck's squad faces crucial club games this month, from promotion and relegation deciders to domestic Cup finals and even a Champions League final, with collective bonuses of more than $3 million on offer. Mile Jedinak's Crystal Palace secured a playoff date at Wembley with Gianfranco Zola's Watford, courtesy of Manchester United-bound Wilfried Zaha. It's believed that Jedinak could be on his way to the Premier League regardless, with Stoke City rumoured to have agreed to terms with the combative Socceroos midfielder for next season. Managed by larrikin former Blackpool boss Ian Holloway, the Palace squad was largely formed by former manager Dougie Freedman -- now at Bolton -- and his then assistant, Western Sydney coach Tony Popovic. Another whose destiny doesn't necessarily hinge on his club's is Robbie Kruse, whose Fortuna Dusseldorf remains in relegation trouble heading into Saturday night's final round. Robbie Kruse playing for Bundesliga strugglers Fortuna Duesseldorf. Fortuna is one spot above the relegation playoff zone on equal points with Augsburg, which plays already-relegated Greuther Furth. Regardless of the outcome, Kruse is headed for Champions League-bound Bayer Leverkusen next season after last week securing a $2 million transfer. Like Kruse, FC Utrecht winger Tommy Oar is becoming increasingly important to Osieck's qualification campaign and could soon have a new home. But after finishing fifth, Utrecht faces a convoluted four-team playoff for a sole Europa League spot. First-up it's Heerenveen, with the winner to take on FC Twente or Groningham in another two-legged playoff. Oar said the crunch games would benefit the Socceroos, with the 21-year-old potentially jetting off to Socceroos camp in Japan the day after his final game. "It would've been awkward timing if we had a few weeks' break but playing at a high level is ideal preparation," Oar said. It's one thing keeping fit by training but being fit and match fit are two different things. If I make the squad, myself and the boys who still have games are in a lucky position going into the camp, we'll have some good match time under our belts. It (the Oman game) was very disappointing, but we got a draw out of it in the end. It's not the result we were looking for but it's important we don't dwell on (it), and most importantly our destiny remains in our own hands. Fellow Aussie Michael Zullo is also in Utrecht's squad, although Adam Sarota (knee) is recuperating. In Asia, Mark Bresciano scored in his comeback for Al Gharafa in its 2-1 Asian Champions League first leg loss to Al Shabab yesterday. James Holland hopes to cap a breakthrough season by claiming the league and Cup double in the Austrian league. Holland's Austria Vienna hosts third-tier side Pasching in the May 31 final.
