Maurizio Sarri admitted his concern as Chelsea crashed to their heaviest defeat in almost 28 years and gave an equivocal answer when asked about his future.

The Italian’s position as Blues manager is likely to come under further scrutiny after they were routed 6-0 at Manchester City less than two weeks on from a shock 4-0 thumping away to Bournemouth.

Sandwiched between those two heavy losses was a 5-0 win over Huddersfield at Stamford Bridge last weekend and Sarri revealed the discrepancy between home and away results has left him bewildered.

He made an encouraging start to his tenure as Chelsea were unbeaten after their first 12 Premier League matches under him this season, but they have faded out of title contention and now face a battle to finish in the top four.

When asked whether he fears being sacked, Sarri replied: “I don’t know, you have to ask the club.

“I am worried about my team, I am worried about the performance but my job is always at risk so I am not worried about the club. You have to ask the club.

“I didn’t see my football (against City). At the beginning (of the season) it worked. So now we need only to understand the reasons why at the moment it isn’t working. We need to understand the reasons.

“It is not easy. At the beginning, we played better away than at home. Now we are playing better at home than away.

“Something is changing. At the moment I am not able to see the reason but I have to work for this because my target is to play my football, not to change another football because at the moment we are playing another football.”

The setback at the Etihad Stadium was Chelsea’s worst result since a 7-0 thrashing at the hands of Nottingham Forest in April 1991.

The defeat clearly got to Sarri, more than others, as right after the full-time whistle, he stormed down the tunnel without even offering his hand to opposite number Pep Guardiola.

After the game, Sarri was asked about the incident, and he responded by saying: "I didn’t see him at the time but I will go to say hello to him later, as usual,’ Sarri explained at his post-match press conference.

"I wanted to go to the dressing room and in the moment I didn’t see him. I have no problem with him."
