So let me explain the title: you have to know why you want to use him. Forget about chemistry, forget about the players you need to link. Think about what you need in a CM.
The formation I use is 5-2-1-2, and sometimes I switch to 4-1-2-1-2. So in both cases he plays in the same position, although with different roles. Anyway, he's a B2B CM that needs to be complete, in other words, he needs to be able to defend, control and attack. And let me tell you: he doesn't let me down.
If you look for the same things that I do when searching for a CM, I'd recommend him. He does the job and is one of my favorite CMs in the whole game. For my gamestyle, I would say he's better than De Jong, Llorente, Pogba, Goretzka, IF Tonali, Sabitzer and some other players I've used this year.
The only reason I don't rate him 5 stars is because he obviously isn't a game changer and is not a the same level as crazy meta cards like RB Nkunku. So if you don't have 250k to spend on a CM, I'd say he's a safe bet. Easily one of the best values for cards in the game (well, you can't really go wrong with 3k).
Just in case you are worried about how good I play FIFA, I got from DIV 2 to the Elite division using this squad.
Sorry for any grammatical mistakes, english is not my first language but I tried to make sure everything I wanted to say was understandable.
