Manchester United have suffered an injury scare to Henrikh Mkhitaryan.

The Manchester Evening News says United will be anxiously awaiting news on the injury status of Mkhitaryan, who was subbed off in the first half of Armenia's friendly with Czech Republic.

The attacking midfielder has a collision with Marek Sukhy, and was withdrawn as a result.

United and Jose Mourinho will be hoping the substitution was a precaution ahead of Armenia's World Cup qualifier with Denmark at the weekend.

Mkhitaryan made an impressive impact when he came on against Hull City, and Mourinho will be desperate to have him available for the Manchester derby on September 10.
