Bayern Munich skipper Mark van Bommel believes his side may well struggle to keep Wayne Rooney at bay as they prepare to meet Manchester United in the Champions League on Tuesday evening.
The quarter-final first-leg will be played at their Allianz Arena home and the Dutchman is prepared for a tough test against last season's losing finalists.
Bayern have lost their position at the top of the Bundesliga table following back-to-back defeats against Eintracht Frankfurt and Stuttgart recently.
Sir Alex Ferguson's Red Devils have chalked up seven successive victories in all competition and sit at the summit of the Premier League but van Bommel is confident they have what it takes to win through.
"It will not be easy to deal with Rooney because he is such a good player," the veteran said.
"We normally man-mark players like him but I don't think we can with him because he is too good.
"We will have to defend zonally so that more than one player can take care of him.
"It will be a very difficult tie because United, along with Barcelona, are the favourites to win the Champions League. I also don't think it is an advantage for us to play the first game at home.
"But we played the first game at home against Fiorentina in the last round and we came through. If we draw 0-0 here and score in Manchester then we will have the advantage."
