Manchester United manager Jose Mourinho has expressed his delight following the arrival of Brazilian international Fred at Old Trafford.
The Red Devils head coach said that the £50m summer recruit will "complement" the club's existing midfielders when he lines up alongside them.
"Fred will complement our other midfielders' qualities, which we need; his creative brain and passing vision will give us another dimension to our game," Mourinho told the club's official website.
"I am very happy he is joining our club and I believe our players know how important he can be in our team."
Fred, who is currently on international duty at the World Cup with Brazil, joined United from Shakhtar Donetsk.
