Manchester United striker Zlatan Ibrahimovic says he will "come back even stronger" after suffering cruciate knee-ligament damage.
The 35-year-old was injured in the final minute of normal time during last week's Europa League quarter-final second-leg win over Anderlecht.
Ibrahimovic is United's top scorer this season, with 28 goals.
"I will go through this like everything else and come back even stronger. So far I played with one leg so it shouldn't be any problem.
"One thing is for sure, I decide when its time to stop and nothing else."
Ibrahimovic joined the club on a free transfer from Paris St-Germain last summer but is yet to agree an extension to his one-year United deal.
