Zlatan Ibrahimovic has suffered serious ligament damage in his right knee and is likely to be sidelined until January 2018 at the earliest.

Ibrahimovic suffered the injury in the Europa League on Thursday.

The injury has now placed doubt over the player's club future, with his United contract due to expire at the end of this season. It is unclear if United is under an obligation to honor the extended contract following his injury.

Ibrahimovic had been the subject of interest from MLS clubs LA Galaxy and LAFC.
