I don't understand why are people so much against him. We're in dire need of a holding/defensive midfielder. We all know Carrick can't play every week and we all know we have no one else who could do that job. Yes, there are probably better targets, but are those better targets attainable?
Matic had 35 appearances for the team that ran away with the title as early as the winter. And that was in a 2 man midfield. Yes the other midfielder was Kante, who's work rate is exceptional. But we do have Herrera as well.
Matic is tailor made to sit in front of the back four. He's popular with his dribble or his agility, but neither is Carrick. He's good at protecting the ball and passing (7 assists in the league last season). His defending is not class A, but he is one of the best in class B.
For the position he is, he could easily play 4-5 seasons, even if he is 29. On top of all he's tall which only boosts our defensive rating.
If he comes in the 30-40m region, it will be a good deal. If he comes for <32m I would call it a very good deal. 25m and it's a bargain.

I think this would be a good signing.
