The Blues were coming off the back of a 5-0 victory over Huddersfield from the game before, but Maurizio Sarri’s side failed to carry their momentum through to their trip to the Etihad.
Chelsea found themselves 1-0 down in the first five minutes after Raheem Sterling opened the scoring. It went from bad to worse for Sarri’s men, with Sergio Aguero grabbing his 11th Premier League hat-trick of his career.
After the game, the Azpilicueta apologized to the fans for a poor team performance
It is one of the worst nights in my career,’ Azpilicueta said.
It is difficult to explain what happened. ‘The first five or six minutes went well but that is not enough. It is very frustrating and disappointing.
We are conceding a lot of goals and we cannot accept that.
When you lose 6-0 we have to accept we didn’t play well and made errors. We knew it would be tough. When we won at Stamford Bridge it was because we played well and were together.
Today was not the case. All I can do is apologise to the fans because it is not acceptable.
Chelsea’s defeat to City was their heaviest ever in the Premier League, and they are now sixth in the division this season.
The club’s next fixture is against Malmo in the Europa League on Thursday.
