Henrikh Mkhitaryan has claimed that he is "not sure yet" if he will be fit to play for Manchester United in this weekend's derby clash against Manchester City at Old Trafford.

The 27-year-old suffered an injury while on international duty with Armenia last week.

The national team's governing body claimed on Saturday that the results of a scan were "not encouraging", but there has been no confirmation with regards to the severity of his thigh problem.

Yesterday, Mkhitaryan took to Instagram to provide an update. He wrote: "I continue extensively my rehabilitation, but I'm not sure yet if I will be fit for the derby this weekend.

"I'm motivated as ever and plan to put all my energy to be in great shape as soon as possible...a simple devotion to what I love most - football! Thanks for sending me your love & support."

Mkhitaryan, who joined United from Borussia Dortmund in the summer transfer window, has had to settle for a regular spot on the bench having played one hour of football so far this season.
