Only goals can boost the fragile confidence of Chelsea striker Alvaro Morata, according to head coach Maurizio Sarri.The Spain striker and the Blues were profligate in Thursday night’s 1-0 win at PAOK in Europa League Group L.Morata began his Chelsea career with seven goals in eight games last season, but has appeared shorn of confidence of late. He has scored once this season, in August’s win over Arsenal.Sarri is scratching his head at how to revive Morata’s morale, but praised his improved movement.“Alvaro has to gain confidence with one, two, three goals,” Sarri said.“I am not able to give him confidence. In this match he has had three, four opportunities. He was unlucky.“I hope for him that in the future I can try to help him, but the confidence can become only with goals.“I have to say also, for maybe the first time in this season Alvaro was ready in the box. He was on the ball and was active.”Sarri knows the task at hand with Morata, who hasn't won over the Chelsea fans since arriving from Real Madrid last summer.Despite starting well, and linking up well with Cesar Azpilicueta, his form has drastically dropped, and he's now deemed second fiddle in the starting XI, behind ex-Arsenal target man Olivier Giroud.To make matters worse for Morata, cameras spotted what he did after being subbed off last night.He seemingly snubbed Sarri and his attempt to comfort him after being hauled off.You can watch the clip below.

If a clip could ever suggest something is not alright, then it is that one.

All eyes will be on whether Morata features for Chelsea this weekend as they travel to the London Stadium to take on West Ham United.

However, one thing is for sure, Morata needs to start scoring.
