I honestly don't know how good this guy is and if it is worth the hassle to get him. I'd rather us spend money in the midfield - Fellaini and Herrera are gone without being replaced, Matic is basically not part of the first team squad and Pogba is leaving after the season ends.
That leaves us with McTominay, Fred and Garner (nowhere near ready to be a first team CM), which is shocking, and Pereira, Mata, Lingard at CAM - not one of them is good enough to be our 10 in the long term.
In that sense, I believe the main priorities should be 2 CMs, 1 CAM and then we should look at a backup striker and potentially a LB, depending on what the situation with Shaw is. Despite being so young, Haaland would want to be a undisputed starter, in my opinion, which would just create problems in the squad.
