Chelsea are set to be without key striker Alvaro Morata for up to 4 weeks after he picked up a hamstring injury.

Morata had limped off in the first half of Saturday’s defeat to Manchester City, and was dropped from the Spain national team after the injury was diagnosed as a grade 2 myofascial injury.

He’s Chelsea’s record signing, having joined the Blues from Real Madrid for £70million in August.
