José Mourinho has admitted re-signing Zlatan Ibrahimovic is an option for Manchester United.

Ibrahimovic is rehabbing a torn ACL and isn't likely to be ready until January.

“Possible, it’s open," said Mourinho. "There was not a new contract [to allow] time for everybody to think, feel and decide. From his point of view he made the decision of wanting to play football still at the highest level. He didn’t want to hide behind such an amazing [serious] injury – it would be easy to hide behind it, stop and go to a different level of football.He made the challenge for himself to keep playing at the highest level.”
