Chelsea vs West Ham Football Match Watch Live, Start Time and More

Speaking at a media conference on Friday, Sarri also pointed to the example of former Liverpool striker Luis Suarez, who took time to settle at Anfield before becoming one of the Premier League's top players.

'Of course it will be hard, but I have to consider in this moment of the season we need to change, ' Sarri said at his pre-match press conference.

Sarri, however, is adamant Abramovich remains a hugely powerful voice - even if his own communication with the Blues supremo is relayed via right-hand man Gianfranco Zola.

But Sarri believes the player's desire is to stay at the club longer, adding: "Yes, I think so".

Sarri's rotation policy is likely to hand further chances to several players who have struggled to find form in recent weeks - most notably Gonzalo Higuain, who has scored just three goals in 11 appearances since arriving on a lucrative loan deal from Juventus in January.

As well as pursuing a top-four finish, Chelsea also remain in contention for the Europa League, and it appears as though Sarri is prepared to call on both Hudson-Odoi and Loftus-Cheek going forward.

"So it's not easy for a striker to play immediately well in the Premier League".

Chelsea were hit with the two-window transfer ban by Federation Internationale de Football Association last month, over breaching rules concerning overseas players under the age of 18.

"We have a lot of young players, very good, they are improving".

The player himself suggested late past year that he would "prefer to be at a big club rather than playing every week in a less prestigious team".

"I think that he has to improve physically (and) mentally".

Hudson-Odoi started his first league game against Brighton and Hove Albion last time out, and Sarri suggested that he could soon earn his second.

Maurizio Sarri's side will now aim to continue on their impressive form as they host Pellegrini's West Ham at the Stamford Bridge.
