Maybe in a year Chelsea will be at Liverpool's level – Sarri

Chelsea was held to a 0-0 draw by West Ham on Sunday and manager Maurizio Sarri thinks that it is a year from being on Liverpool's level.

Maurizio Sarri does not think Chelsea will be at the same level as Liverpool for another year following its underwhelming 0-0 draw at West Ham.

Chelsea started the Premier League season with five successive victories, but in Sunday's London derby, it was frustrated by a dogged Hammers side.

Sarri's men were dominant, though West Ham actually crafted the better chances, with Michail Antonio and Andriy Yarmolenko both wasting glorious opportunities.

Things are not about to get much easier for the Blues, which faces Liverpool in an EFL Cup and Premier League double-header in the next week.

And, Sarri thinks that league pacesetter Liverpool – which has won all six of its league matches so far – is a cut above his Chelsea team.

"We have to face a team, a very, very good team that has worked with the same coach four or five years, I don't know exactly," Sarri in his post-match news conference.

"They are a step forward than us at the moment. We started to work together 40 days ago and [have had] less time with the international [break]. For us it is a bit early. We have to work and improve and then, maybe in a year, it will be the same level as Liverpool."

Sarri is not convinced Chelsea's Europa League trip to PAOK had anything to do with Sunday's sluggish performance, though he does not see why the Premier League cannot do it a favour with match scheduling.

"I don't know, I don't think so. In this period, I don't think so. After seven matches it is difficult in March and April, not now. I don't know why in England with the match away you can't ask for a Monday night. In Italy it is normal," he said, when asked if Chelsea were suffering from a European hangover.

Centre-back Antonio Rudiger was forced off with an injury in the second half, as he started to hobble around the pitch. Sarri does not expect it to be a serious problem, however. "I want to speak with the doctor. I think [it's] nothing serious. Maybe three or four days [out]," Sarri added.
