Offcourse what's better than one average player two of them .
Ps Mctominay is nowhere good enough for United but neither is Fred as regular starter.
Fred is fine. He plays with McTominay who is a net negative almost every game. He effectively plays in a one-man midfield which is always going to affect his performances. If we have another player who offers everything Fred does or more, I'm sure we'd see plenty of improvement in performances.
He is good with his long and short passing, shows for the ball, carries the ball, keeps it moving well and puts in plenty of defensive work. Although he has the occasional lapses in concentration, he retains the ball well, and I've seen him take control of the midfield battle many times.
It is difficult to be really good every game when he has to do twice the defensive job that McTominay does, and twice the job he does on the ball too.
I have seen Fred have plenty of games where he showed everything that you'd want from a Manchester United midfielder, and his skill set is accomplished for a Premier League midfielder. For where we want to be, Fred is absolutely good enough as far as I'm concerned.
