Paris Saint-Germain head coach Luis Enrique has urged his side to be brave in Tuesday's Champions League clash at Bayern Munich, admitting their stuttering start leaves no room for error.

PSG are languishing just under the play-off section of the Champions League standings in 25th, having won one, drawn one and lost two of their four matches to date. Bayern are 17th with two wins and two losses.

The difficult start to the campaign has made things more challenging for the Ligue 1 leaders, Luis Enrique said at his pre-match press conference on Monday.

"It's obvious that after four matches, including three at the Parc des Princes, with fair or unfair results, unfair for me, we have to have good results to qualify," he said.

"We made things difficult for ourselves. Football is what it is. You have to score.

"We will give it our all, we will be brave, we will take risks, as we usually do."

Bayern have won their last three games against PSG in the Champions League, with the French side failing to score in each of those matches.

Luis Enrique accepts it will be a tough match and that his side need to perform above and beyond.

"It is very clear that we are two teams that are similar. We want to have the ball, we press very high... we have similar statistics," he said.

"We are among the best teams with goal chances, but there will only be one ball. And so one team will have to suffer. Them, or us.

"We'll probably have to go further against Bayern. Run more, raise the level, especially against Bayern at home."
