VfL Wolfsburg manager Lorenz Gunther Kostner is remaining cautious of Fulham ahead of tonight's Europa League quarter-final second leg.

The Germans go into the home leg 2-1 down and although Kostner understands his team needs to attack, he expects a determined performance for a full 90 minutes if they are to get the job done.

"We can't go hell for leather on Thursday," said Kostner. "Fulham are a compact dangerous team who are strong in defence and have big guys up front so that provides us with a dangerous situation.

"We have 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.

"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."
