The France World Cup winner has made no secret of his desire to leave the Reds and neither has his agent, Mino Raiola.
"He's a great person and a great player," Fred told UOL Esporte. "On a daily basis we [are] together a lot. He's a good guy and we try to bring him closer to United.
"Unfortunately, he was injured a lot this season, but he can still help a lot.
“Needless to say, he is a great player. May he recover quickly, because he is world champion and being 100 per cent will help us a lot."
"He has his personality, but that shouldn't get in the way of any analysis," he added.
"We feel bad because of the injury.
"His way of being does not change the good person and the great player he is. He's a very hard-working guy, who struggles to get back soon."
