Fonseca: 'Fred will come good at Man United'

The two worked together in the Ukraine, winning back to back doubles as well as progressing in the Champions League. 

"He's a big talent and he's still developing," Fonseca said to 'ESPN FC'.

"I have no doubt he'll have a great future at Manchester United. But, of course, he needs time. It's totally different from what he was used to in Ukraine. He needs a period to adapt, to the club, to the league. It's a totally different situation.

"In my opinion, his position is in a midfield two as the more attacking of two central midfield players.

"He is physically strong and mobile, with the quality to build play, but he is also very good at breaking from midfield and going to either side of the attack."
