For the third successive home game, Thomas Tuchel walked into the small media room at Stamford Bridge and delivered a post-match press conference full of frustration, irritation and exasperation. The Chelsea head coach made no attempt to hide his emotions.
"We thought we learned our lesson from Brentford and Real Madrid, but obviously not," Tuchel said after his side's 4-2 defeat to Arsenal. "The players have to face the reality that it's impossible to win matches if you make this amount of mistakes – and mistakes of this calibre. It's simply impossible. I haven't seen it in any other matches, but I see it now in consecutive matches of our games, and it has to stop."
Chelsea will have an opportunity to put things right on Sunday against West Ham United. It's another London derby against a side pushing hard for a top-four finish in the Premier League. The Blues will not have it easy as they attempt to end a disappointing run of results at Stamford Bridge.
