The 34-year-old joins today for the first time the training with his new squad and Jose Mourinho.
Ibrahimovic returned after his vacations, which he spent in Miami.
He's been training on his own with a private trainer since Sunday and meets his team-mates for the first time.
But he's not the only one to join the training for the first time: Bastain Schweinsteiger, Morgan Schneiderlin, Anthony Martial and Marouane Fellaini returned also from their vacations.
This training in Carrington is the first time that Mourinho can see his whole team together and motivate them.
