Arsene Wenger has slammed Paris Saint-Germain after their defeat by Manchester City in the Champions League.
Riyad Mahrez's free-kick went through the wall to give Manchester City a 2-1 lead heading into the second leg of their semi-final tie next week.
PSG's hopes suffered a further blow when Idrissa Gueye was shown a straight red card for an ugly late challenge on Ilkay Gundogan.
And Wenger believes PSG’s second-half collapse was due to their poor discipline.
Speaking about Mahrez's free-kick, Wenger told beIN SPORT: “From the defenders turning their back, it’s between Paredes and Kimpembe. Why do you lie a guy on the ground if the guys in the wall open the wall?’
“I personally believe that the second goal is not acceptable for that level. It's not the first time we see players turning their back and City took advantage of that.
“But I must say in the second half PSG were protective and not progressive any more. Is it because they were not physically capable?
“After the 1-1, they collapsed completely. They become emotional and aggressive in a stupid way.
“You could see the confidence dropped considerably and the mental impact when Man City equalised, for the semi-final of a Champions League, was too big.”
