The former Juventus midfielder was among a handful of United players who only returned to pre-season training on Monday, after their countries advanced to the World Cup semi-finals.

"He had nine days of pre-season where no training, no football, absolutely nothing".
The Premier League season kicks off tonight when United host Leicester City and all eyes will be on Mourinho.
He added: "There are ways to improve your team: one way is to spend a lot of money and to bring in lots of important players, another way is to work and that's the way we have to do it".
"When you repeat 1,000 times that my relationship with my players is not good, it's a lie, repeated 1,000 times is still a lie".
