The Argentine recently made his long-awaited comeback from a foot surgery and he lasted for only four games before picking up a knee damage.

The centre-back does not require a surgery for the setback, but it will take at least eight weeks for him to fully recover, as per United's website.

This is a huge blow for the Red Devils, who are eager to qualify for the Champions League. They face a big hurdle at the current point.

The club are already eight points behind the top four and they need to go on a long winning run in order to cut the deficit on Aston Villa .

United will be at Villa Park this weekend in what will be a make-or-break game in the top four race. Martinez's absence will be felt.
