Paris Saint-Germain face Dinamo Zagreb in the Champions League on Tuesday, with coach Carlo Ancelotti keen to get their campaign back on track after defeat to Porto.
Ancelotti saw his side fall to a 1-0 defeat in Portugal after having won their opening Champions League game at home to Dinamo Kiev 4-1.
And he urged his big-money stars to raise their game for the challenge in Zagreb, saying: "It's an important game.
"We want to get to the next round of the Champions League, but I do not know what we can do in this competition. I trust, and I hope, we can go far.
"To win a match in the Champions League takes strength and concentration."
An injury to Brazilian winger Nene means Javier Pastore will play behind Zlatan Ibrahimovic and Jeremy Menez, and Ancelotti said: "I hope that Pastore will have a big game, show confidence and demonstrate his capabilities."
