The loss follows heavy home defeats to Brentford and Real Madrid, which were also blighted by individual errors from Chelsea’s previously reliable defence.
Andreas Christensen’s poor back pass set the tone, allowing Eddie Nketiah to score the first, and he got his second after Emile Smith Rowe’s well-worked strike following a turnover, before Cesar Azpilicueta gave away a late penalty for holding onto Bukayo Saka in the box.
“It was a totally wild and open game in the first half – already a 2-2 after we came back twice. We had a good start but again gave the first goal away, which is impossible to do these things in consecutive matches. But we’re doing it. We came back twice, and we scored another two in the second half, unfortunately for the wrong side.
“It’s a level of mistakes, the number of mistakes in consecutive games here at home, it’s impossible at this kind of level. You don’t see this. It’s simply impossible, but we’re doing this at the moment, and you cannot win football games like this.
