PSG goalkeeper Gigi Buffon is demanding his teammates buck up their ideas after their 1-0 win over Bordeaux.

Buffon says their attitude wasn't good enough ahead of Tuesday's Champions League round of 16 first-leg clash at Manchester United.

He said, "I did not like the match because we have to improve our mentality and our attitude, the spirit of sacrifice for the team.

"Because Tuesday (against Manchester United), they will wait for us a very important match and we will have to make a big match. I think it is necessary to improve because we are going to play against a team that will impose a tougher challenge, which will have a different attitude."
