Manchester United's Henrikh Mkhitaryan has admitted that he is "not sure yet" if he is going to be fit for the derby against Manchester City on Saturday.
The Armenia midfielder, 27, limped off during their 3-0 away defeat against Czech Republic last week.
The Armenian FA released a statement, after medical tests, predicting that he would need "a week to ten days" to recover, and the player missed Sunday's 1-0 defeat against Denmark.
And Mkihtaryan wrote on Instagram on Tuesday: "We win and lose together. I'm very disappointed to have missed the game against Denmark, but I'd like to thank the team for their hard work.
"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."
