Mourinho has come under fire this week after Manchester United were beaten 3-2 by Brighton last weekend. The defeat comes after a difficult summer in the transfer window where Mourinho failed to get the players he wanted.
Fred was one of just three signings made by United and has been thrown straight into action by Mourinho.
But the Brazil midfielder has hailed Mourinho for his communication and hopes the two-time Champions League-winning coach remains at Old Trafford.
“I’m really happy to be working with Jose Mourinho he’s a great person and he’s always keen to communicate with the squad and help people to be communicative regarding what they’re to do on the pitch,” Fred told Sky Sports.
“I’m really happy to be working with him and I hope that I’ll be working for him for a while to come.”
Fred has started United’s first two Premier League games alongside Paul Pogba and Andreas Pereira.
And the 25-year-old has opened up on the help he’s received from Pereira and Mourinho in terms of the language barrier.
“There are lots of Brazilians in the Premier League but most are playing against us,” he said.
“Here I’ve got Andreas (Pereira) who is here at Manchester United, who has helped me a lot and been important to me and, obviously, Jose Mourinho speaks the same language.
“I’ve been adapting here with my team-mates at Manchester United and, yes, this has helped a lot.”
After defeat to Brighton last weekend, United face Tottenham on Monday in a mouthwatering clash. And Fred says United have to get back on track.
“It’s a very important game,” he said.
“This week we’ve been working, focusing on this game, we want to go out and get the win in front of our home fans.
“We know Tottenham are a great team but we need to get the win if we are to aspire to win the league.”
