Thomas Tuchel walked out of his post-match interview following Chelsea's defeat by Arsenal before taking aim at the Stamford Bridge pitch.
The German saw his side ship four against the Gunners in what was a frustrating evening for the Blues. They twice went behind and drew level before Arsenal scored two in the second-half to seal the three points. Tuchel was left bemoaning defensive errors in the defeat.
Andreas Christensen's mishap allowed the north Londoners to take the lead in the first-half with the Chelsea boss claiming they scored five of the six goals - three of which they gifted to Arsenal. He also admitted he "didn't know" how to react to the reverse in a blunt debrief.
He began by saying on Sky Sports: "We scored five goals and lost 4-2. Three own-goals and two regulars goals for us. I cannot remember any mistakes like these in our favour. We don't get these goals we give them away in consecutive games.
"Second-half was nowhere good enough. Individually, how we conceded the goals it is dramatic mistakes, individual mistakes. We decided to give away a goal for absolute nothing - we did the same against Real Madrid and against Brentford."
Tuchel handed a start to Romelu Lukaku, who has been in and out of the first-team, and was later hauled off, but the German refused to discuss his forward's display. He claimed: "I have no interest in individual discussions after a team performance like that."
Does Tuchel have a point about the Stamford Bridge pitch? Let us know in the comments
Tuchel proceeded to end his interview before citing issues with the Stamford Bridge turf as he addressed the written media. The German referenced goals they conceded in defeats against Real Madrid and Brentford at home as proof that the pitch in west London does not favour them.
He claimed: "The pitch is difficult to play here, that may sound like an excuse but it is very, very difficult to play on the pitch we have here - it is not to our favour. The ball bounces very awkwardly in front of Andreas (Christensen), but we had the same mistake against Real Madrid. That cost us the next round of Champions League, this one cost us this match."
It would take an almighty collapse from Chelsea to relinquish third place, but they have now lost two of their last three league matches. Next up for the Blues is another home game, this time against West Ham, where the pitch will be under the spotlight following Tuchel's damning assessment.
