Paris Saint-Germain manager Mauricio Pochettino has labelled his side's performance against Monaco in Sunday's Ligue 1 defeat "a disgrace".

After losing Lionel Messi to the flu before the trip to the Stade Louis II, the runaway Ligue 1 leaders were torn to shreds by Philippe Clement's side in a humbling 3-0 loss.

Wissam Ben Yedder struck twice either side of Kevin Volland's effort to hand Monaco a memorable win, and Pochettino has blasted his players for a lack of "fighting spirit".

Speaking to the press after the defeat, Pochettino said: "It's unacceptable to start a game like that. After that, it was a disgrace in sporting terms.

"Now it's time to move on, get over the frustration of the Champions League and think about giving our best while having a competitive attitude. I don't want to look for excuses.

"The first half was unacceptable. We had no fighting spirit. The way we played is not acceptable. This can't happen. We can't have this kind of attitude. It is unacceptable to start the game in this way. Respect for the club and our fans is fundamental. The important thing is to find solutions.

"Behaviour must be more collective than individual. We have moved away from that. We have to think collectively."

PSG's lead at the top of the table has now been cut to 12 points after Marseille's 2-1 victory over Nice later on Sunday.
