Manchester United midfielder Fred admits playing with Bruno Fernandes is "awesome".
Fred could start alongside Fernandes in the first leg of their Europa League last-16 clash against AC Milan.
He told O Clube: "It's awesome having Bruno as a team-mate. A guy who came here at the beginning of last year, we've been together ever since.
"It's turned out that we made a nice relationship on and off the pitch. It is so cool.
"He's a leader. Inside the locker room, despite arriving recently, he is a leader. He's a guy who doesn't like to lose at all - not even in (training game) 'odds and evens'.
"I root for him a lot. I'm sure he will continue to help us, seeking to improve every day. He's a guy who works a lot."
Fred also added what he felt was Fernandes' 'differential' trait to set him apart from other players.
"I think he is very smart on the pitch, you know? He thinks so fast. He can find a pass that no-one can, in that moment, and he has a very quick reaction to find that pass.
"Sometimes the ball goes to him and, with only one touch, he can make the striker face the goal. That is what makes him different.
"This helps him a lot to score goals and assists, his mind speed."
