At first I wasn't keen because I don't think he's top quality and I still dont. He's better than McTominay and much better than Donny van de Beek. The number of games are ridiculous and players like him can always come into use.
So on that basis in terms of adding to our options it's starting to look a fairly common sense option for a cheap fee. I wouldn't spend a lot on him, Bayern don't need or want him.
I don't think he eliminates our need for further midfield options because he doesn't substitute for Casemiro and he still leaves us with weak areas in our midfield where we don't excel. Especially building up from deep, a lot is on Eriksen, probably too much.
For me we have Casemiro (DM), Eriksen (playmaker), Fred (Box to box), Sabitzer (box to box I guess), McT (box to box). So from that point of the view the balance is weird, we could do with getting money for McT and adding some more variety.
