The midfielder feels that Sami Hyypia's men need to rattle the Sweden international but acknowledges that it is impossible to "take the striker out of a match completely"Simon Rolfes says that Bayer Leverkusen will have to do everything they can to put Zlatan Ibrahimovic off his game if they are to have any hope of upsetting Paris Saint-Germain in the last 16 of the Champions League.
The Germans host the Ligue 1 leaders on Tuesday evening well aware that their prospects of reaching the quarter-finals hinge on nullifying the threat posed by the visitors' star striker.
"You can't take Ibra out of a match completely," Rolfes conceded during a press conference on the eve of the first leg at the BayArena. "But we have to be a menace for him and constantly annoy him.
"Everybody has to play to his limit and then we will see if that is enough to trouble PSG.
"They are the favourites, but we are a confident challenger. If we play with our heads held up high, what happened against Manchester United [a 5-0 home defeat in the group stages] won't happen again."
Sami Hyypia also admitted that his primary objective in the build-up to the game has been trying to come up with a way to deal with Ibrahimovic.
"Even if you play perfectly against him, he is able to score a goal at any time," the Finnish coach confessed.
"We have to stop him collectively and make sure he gets the ball little."
Leverkusen's clash with PSG will kick off at 20:45CET.
