Manchester United midfielder Henrikh Mkhitaryan has suffered an injury while on international duty for Armenia and is a doubt for next weekend's Manchester derby at Old Trafford.
The Armenian FA confirmed that their national captain suffered a thigh injury during the team's 3-0 defeat to the Czech Republic on Wednesday and is expected to be on the sidelines for 10 days.
Although it has already been confirmedthat the 27-year-old will miss Sunday's World Cup qualifier against Denmark on Sunday, he is facing a race against time to be fit by September 10, when Manchester City visit their cross-town rivals.
"As reported, senior national team captain Henrikh Mkhitaryan received an injury against Czech Republic and as a result was unable to continue the match," a statement released by the Armenian FA read.
"Mkhitaryan has had a medical examination in a clinic in Mlada Boleslav. Unfortunately, the results are not encouraging. Mkhitaryan was found to have an injury in the lower third of the left thigh muscle.
"Such injuries usually require a week to 10 days to heal, which means that Mkhitaryan will miss the Denmark-Armenia match on September 4."
Mkhitaryan joined United from Borussia Dortmund in the recently-concluded transfer window, but hasn't started a match in the Premier League for Jose Mourinho's side yet.
City will be without star striker Sergio Aguero in the derby, after he was slapped with a three-match ban for elbowing West Ham's Winston Reid.
