It really depends on the outcome of our season. If our season turns bad, then we'll definitely need him. If we have a good season, then he will do more harm than good.
If he does come back(i just don't see this happening, probably we will sell him for an even a lower price). We wouldnt have other optin than support him, like any other Barca player
Of course I don't want this to happen after what happened this summer
The only possible way him to come back if Pep was sacked. But the fans/players would be too much confused and the player himself I am sure will never come back to Barca.
he could potentially come back as pep is out of a contract and if he does not resign zlatan has the potential to come back, but i think milan are obligated to buy him
Only way he could come back is if Pep resigns AND Milan doesn't exercise their option to buy. So it's a very slim possibility.
Either way, I wouldn't want him back. He doesn't suit Barca.
