I think we'll get Ugarte and he'll be great for us. If his ability to win the ball and shut down attacks before they get troublesome isn't overblown i think he'll be a very nice addition to the team. Based off what I've seen of him as well he can at least carry the ball to beat a press unlike current Casemiro who's very static.
He doesn't have to be an elite passer, imo we've got enough of that in the first XI. Players like Martinez, Fernandes, Dalot, Shaw (when fit) and imo Mazraoui as well are capable of pinging the ball around the pitch. Mainoo and both fullbacks are more than capable of getting into midfield and helping with the build up play. Just let Ugarte be the bulldog in midfield, if he's half as good as a Casemiro at his peak then he'll be a great signing. I think he'll be in a Man Utd shirt by next Saturday.
