Playing devils advocate here - but surely it is in our negotiation ( for AS ) interests to say this injury is no big thing .....
Just a thought
It would, but if we wanted to do that, why not go the whole hog? Say on the official site that it's minor, he'll be gone a fortnight, wrap up a deal for Sanchez and then say it's worse than expected, these things take time to become apparent sometimes, new scan's have revealed... etc.
It doesn't make sense to say he's got the MCL injury officially if we were trying to negotiate, and I doubt Jesus would be in on it anyway.
