I think your comment about us being nervous and unsteady is accurate as far as the last game goes but in all reality, that was the first time that Fred has played alongside Bruno and Pogba. With more time I have no doubt the team would benefitI can see that its quicker but it feels kind of nervous and unsteady to me.
Matic can own a certain area of the midfield leaving Pogba and Bruno to try and own a different area relative to them.
I like Fred when we dont over complicate his role & ask him alongside the rest of the midfielders to be energetic and press. Usually mstic and Pogba cant do this but Mctomminay and Bruno can. I like Fred with Mct and Bruno but not with the others because players like Pogba and Matic have attributes that need to be addressed when playing alongside them in my opinion.
I think because Matic is so silky on the ball people often don't notice his flaws. He takes far too long to release the ball and also is constantly caught on the ball in compromising positions. I like Matic and think he's a great player to have in the squad but I think Fred would be more complimentary to our style of play.
