All was well for Chelsea and Maurizio Sarri just a matter of months ago.

After replacing Antonio Conte in the summer, Sarri lead his new side to an unbeaten start to their Premier League campaign.

Chelsea tasted defeat in England’s top tier for the first time this season in November, losing 3-1 to Spurs.

And, ever since that loss, Chelsea have struggled.

Major concerns were raised when the Blues lost 4-0 to Bournemouth a few weeks ago and, they would suffer another massive defeat on Sunday.

Chelsea travelled to the Etihad Stadium to take on Manchester City as the underdogs, but they turned in a hopeless performance as they were defeated 6-0.

That was their heaviest defeat for 28 years.

Understandably, Sarri was unhappy with his players following the result.

The Italian manager has called out his players on numerous occasions so far this term, often describing them as difficult to motivate.

And, a report from the Times shows that he’s had enough of his players.

Sarri’s future at Chelsea is in doubt but, if he continues in his position, it is believed that he will push for a major overhaul of his squad.

The report reads: “Maurizio Sarri is worried that he lacks the players to implement his game plan at Chelsea and will push for a complete overhaul of the squad this summer if he remains in his job.

“The Italian head coach has reached the point after four successive away defeats, including the club’s two heaviest reverses of the past 27 years, where he feels that Chelsea must either back him or sack him, as he is incapable of obtaining the necessary improvement from the players at his disposal.

“Sarri is an advocate of a fast-paced, possession-based style of play that became known as Sarri-ball during his time with Napoli. It relies on strong physical commitment and acute tactical understanding from his players, something that he has concluded is missing from the squad he has inherited."

It seems that if Sarri gets his way, there could be widespread changes to the club's playing staff in the summer.
