Chelsea's season so far has been good, but it could have been even better. Maurizio Sarri has done a great job of turning Antonio Conte'ss team of flops into a fluid, exciting Premier League outfit, but that hasn't extended through to his entire playing squad.

Indeed, there are a few members of Sarri's team that, thus far, just haven't been up to par.

Be it through a lack of confidence, quality or, indeed, just general lack of form, it's down to the manager to improve things and help take the club to the next level.

Chelsea are fortunate that even their most out of form players have still played a role, but nonetheless, there is real room for improvement for Maurizio Sarri's players.

With that said, it’s obvious that these 2 Chelsea players simply haven’t been good enough...

Alvaro Morata

What else can be said about Alvaro Morata that hasn't already been mentioned before?

The Spaniard has been simply terrible so far this season, leaving Chelsea's attacking threat resting on the shoulders of the players around him. He's regularly been dropped in favour of Olivier Giroud, and given how much money was spent on Morata, that's surely very frustrating for the club.

He's scored just 2 league goals, and he's looking like a shadow of the player that looked so good towards the start of last season.

His link-up play is non-existent, his goalscoring is poor, his work rate is minimal - it's just not been good enough.

Cesar Azpilicueta

This is a controversial one, and it's not entirely his fault, but it's hard to say that Cesar Azpilicueta has been the model player so far this season.

It can be put down to him being forced to play in another new position, having spent time at left-back, right-back and centre-back over the last few years, but the Spaniard hasn't quite reached the levels that he enjoyed under Antonio Conte yet.

He's never been a particularly great option going forward, but his presence on the right-hand side of the pitch does reduce Chelsea's impact in that way when he plays.

However, perhaps more concerning is his defensive form. He's made a few mistakes and hasn't been his characteristically solid self. It's nothing to be worried about just yet, as everyone struggles sometimes, but he needs to pick it up.
