Wolfsburg fear Dzeko will move to England

Wolfsburg manager Lorenz Gunther Kostner admits he is unsure whether star striker Edin Dzeko will be able to resist the temptation of a move to the Barclays Premier League this summer.

Manchester City and Chelsea are reportedly interested in signing the Bosnia international, whose prolific form last season saw him linked with a move to Serie A giants AC Milan.

The 24-year-old has continued his emphatic record in front of goal this term by scoring 18 league goals to help rescue Wolfsburg's faltering Bundesliga campaign.

He apparently has a clause in his contract that would allow any would-be suitors to take him away from the Volkswagen Arena for £36million.

Chelsea's ageing strikeforce would make Dzeko a prime target for Blues boss Carlo Ancelotti this summer and Kostner admits the striker must clarify whether he wants to leave the club.

"There are rumours flying around about Dzeko not just in England, but in Spain and Italy as well," said Kostner ahead of his side's Europa League clash with Fulham tonight.

"Edin Dzeko will finish the season a Wolfsburg player, that's for definite, whatever happens after that is down to rumours.

"Edin Dzeko saying he will stay would be an absolutely huge sign for us. I can't tell you how important that would be for us, but that's neither here nor there. Right now we have to wait to see what happens in May.

"All I can say at the moment is that he is on absolute top form. He's really firing on all cylinders. He's doing fantastic."

Dzeko will line up alongside his Brazilian counterpart Grafite against the Cottagers tonight as Wolfsburg look to overturn a 2-1 deficit from last week's first leg at Craven Cottage.

Fulham had looked to be coasting towards their first Europa League semi-final after opening the scoring courtesy of goals from Bobby Zamora and Damien Duff.

Alexander Madlung's last-minute header gave the German side a vital away goal though and Kostner has called on his team to give their all to set up a last-four tie with either Hamburg or Standard Liege.

"Madlung's goal gives us a good chance now but what we need to do is to be determined. We have to have the will, be determined to give an absolutely excellent performance," said the 58-year-old.

"We need everyone in this club, including the fans, to give a performance for 90 minutes, maybe longer and that's the way we'll get through to the semi-finals."
