The Chelsea striker hasn't featured for the Blues since being sent-off against Norwich City in January, with the Blues unsure of when he will be fit
Chelsea striker Alvaro Morata is fighting a mysterious lower back injury as he races to be fit to face Barcelona in the Champions League on February 20.
Morata has not featured for the Blues since being sent-off against Norwich City in the Blues's FA Cup third round replay on 17 January.
And Chelsea boss Antonio Conte was far from reassuring when addressing Morata's status on Friday.
"I don't know [when he'll be back] because he has this problem and we tried a lot to find a solution to solve the pain in his back," Conte said.
