Arsenal midfielder Henrikh Mkhitaryan is set to miss six weeks after fracturing a metatarsal in his right foot, the club have confirmed.
Mkhitaryan was substituted at half-time in the Carabao Cup defeat to Tottenham on December 19 after colliding with Lucas Moura.
The Armenia international subsequently missed the 3-1 win over Burnley on Saturday and Arsenal have confirmed he will be unavailable over the busy festive period after suffering a fractured metatarsal.
Mkhitaryan is expected to return to training at the start of February and is set to miss crucial league games against Liverpool and Chelsea.
He could, however, return in time to face Manchester City at the Etihad on February 3.
