To give you an idea, ive posted this 100s of times now but for belgium he plays behind 2 midfielders.
So hes the midfield anchor between midfield and defence
He doesnt run around alot like Gana (who leaves massive gaps behind him), he sits in his zone mostly and moves forward as the midfield and defence move forward.
His defensive game is about interceptions and covering his area of the pitch with tackles using his long legs. His passing is class whether long or short so he can control the game in a way.
Also for belgium hes allowed to drive with the ball which Dyche you can see and hear at the game shouts and gestures him about. Its happened twice recently that i can make out from the screen where dyche is yelling and waving his arms so Onana stops dead, passes and goes back to position.
But with us of course we dont play with 2 midfielders in front of him. We play Onana left and Garner right midfield with Doucoure god knows where lol
Mt Busquets example is simply to show the style they both have is similar and its not effective in this setup. Imagine Busquets playing left with Garner right...hed be out of place.
Essentially hes quality but hes no CM.
