He only needs time to build his condition again. It can’t be overstated how important a proper pre-season is, the first day back last summer he had to be rushed into some mysterious operation after his physical tests and he missed the whole thing. That’s following on from 6 months of injuries, illnesses, surgeries and the resulting complications.
He hasn’t done his knees or anything that should prevent him reaching his best level again, as far as we know. I think he can earn a new contract here if he gets into shape ready for next season, he can still be a very good player for us.
