Alvaro Morata has made a quite incredible start to his Chelsea career.
Seven goals in eight appearances in all competitions says it all really as the former Real Madrid man has settled into life at Stamford Bridge perfectly.
But on Saturday evening, he had his toughest test of his Chelsea career so far - a match against Pep Guardiola's Manchester City.
During a cagey opening 30 minutes, the Spanish striker didn't get too many opportunities to show off his superb finishing ability.
However, he was able to show off one ability - the ability to embarrass defenders.
When one-on-one with John Stones early on, Morata completely turned him inside out - totally confusing the poor young defender.
It resulted in Morata winning a corner but Stones was probably left wondering how Morata had done it.
Take a look:
And just check out the reaction on Twitter:
Unfortunately for Morata, that was one of his last involvement in the game. Shortly afterward, he was limping off the pitch with what appeared to be a hamstring injury.
Did he pick it up whilst humiliating Stones?
While we're not too sure how Morata suffered his knock, it appeared as though everyone already knew he was carrying it.
He walked off the pitch straight away without any questions being asked of him with Willian replacing him.
If he has pulled his hamstring, it could be very costly for the Blues. Luckily they will have a two-week break due to international matches. During that time, they will be hoping Morata can recover.
