"I am working very hard and my whole thoughts are with Ipswich Town away on Wednesday, and travelling down to Brighton in the FA Cup at the weekend. You couldn't say that about Chelsea in the past, but this looks like a weak team".
City have now scored 33 goals in their last five home games in all competitions and have a chance of lifting their first silverware of the season when they face Chelsea again at Wembley in the League Cup final on February 24.
"Whether he can do that remains to be seen because they're playing Manchester United in the cup, the League Cup final coming up and four or five games in the next couple of weeks so I think he needs to put it right otherwise he will be walking".
The result dropped Chelsea to sixth in the Premier League and raised fresh questions about Sarri's job security, but he was bullish about the prospect of an Abramovich phone call in a post-match interview with Sky Italia. The city official later apologised to their Chelsea counterpart in hope of avoiding frosty relations.
There remains much debate about Jorginho's arrival and what it's meant for N'Golo Kante.
After losing 2-0 to City in the Community Shield, Chelsea went unbeaten in 18 games.
Chelsea captain Cesar Azpilicueta added: "It is one of the worst nights in my career".
"When you lose 6-0 everyone has to accept they didn't play well".
Aguero said: "I am happy for the hat-trick and to break records in the Premier League and for the club".
All four goals conceded at Bournemouth came in a second-half collapse, while City hit four inside the first 25 minutes at the Etihad. The only relief during that period was a 5-0 victory over bottom side Huddersfield, at home. Sergio Aguero then helped himself to a hat-trick and Ilkay Gundogan also got on the scoresheet before Sterling completed the rout with his second.
"To score six against Chelsea and the way we played, we had so much attention (to detail)".
Aguero's afternoon could have been even more profitable as he missed a sitter in the early stages and later headed against the bar. They outclassed us. It was a collective failing. "Chelsea are certainly a club I respect, and have a manager I respect", said the Derby County manager.
"It's a great disappointment and we have to react".
"We are conceding a lot of goals and we can not accept that".
