Chelsea boss Frank Lampard called their first half performance ‘painful’ as they were easily beaten 3-1 by Man City.
The Blues looked decent during the first ten minutes but were soon figured out by Guardiola’s side.
Ilkay Gundogan put the away team in front early on and City dominated from that point onwards.
Phil Foden and Kevin de Bruyne piled on more misery for Lampard by scoring to make it 3-0 at half time.
Callum Hudson-Odoi scored in the second half but it was no more than a consolation goal.
The loss was one of the worst of Lampard’s reign and showed the gap they have to make up to become genuine title contenders.
Speaking to BBC Sport after the match, Lampard said: “Mistakes, individual mistakes, not getting close enough. They punished us. If you want to reach the top level, which City have been for a few years now, you have to accept the pressures. The second half we competed but at 3-0 the game was pretty much done.
“I am not trying to talk up the last 20 minutes of the game because at 3-0 the vitals of the game have changed, but I was still looking for a reaction.
“I am not putting ourselves down. I am the man to have the reality check and there will be work and at times pain. Today was painful in the first half in football terms because their level of play showed where we need to aspire to. In the second half I saw a reaction but the work needs to be done.”
Chelsea fans will be hoping for a return to form in their next few matches. The Blues face Morecambe in the FA Cup next Sunday. Their next Premier League match is against Fulham on Friday 15th January.
