If he did, it was his right to do so, but there was no reason to lie us, promising that he wants to stay no matter what. Zlatan and Vieira wanted to play for the ones who framed us, but at least they never lied about it, its unprofessional to do so and he has no excuses if he did that intentionally...
Now we were the ones who forced him out, then this changes everything.
As for his value, he is useful now, but hopefully we wont regret in the future...
Its not the first time we have overlooked a permanent fix for our weakest spot.
