Milan not happy with Ibrahimovic

He's not having his best season Swede Zlatan Ibrahimovic, far from it. Before the Lecce gam, he warmed up but couldn't play after he felt a twinge in his feet. He was injured once more.
The forward is suffering, according to latest reports, from a calf problem. Due to his serious knee injuury, he may have overworked his right leg, causing this new hinderance.
According to 'Il Corriere della Sera', the footballer wasn't up for undergoing tests, something which AC Milan obviously didn't like, as they want to know exactly what's up.
Before, the source openly criticised Ibrahimovic. They claim that he's going through "dark days" and that "his mentality and attitude aren't right".
Ibrahimovic hasn't played since the 24th March. He got injured with the Sweden national side in a game against Belgium which, to add insult to injury, his side lost 0-3. It was then his thigh that forced him to stop and it seems now that it's the calf which is the source of his pains.
The Milan file is open. The Italian press are claiming that something has happened to the 41 year old, and that his side don't like his attitude. AC Milan are currently fourth in Serie A and go up against Roma in the latest matchday.
