Admittedly, I've not watched much of him, but from what I've read, and clips I've seen of him, he's more a ball playing number 8, who has the ability to bypass the midfield, either by line-breaking passes or progressive carries. Similar to Mainoo, if you like.
A first phase midfielder is who, in my opinion, we should be targeting. Someone like Rodri, and if he didn't pick up a bad injury last season, I would have loved to have seen us go in for Boubakar Kamara, who I wanted as a free agent when he was at Marseille.
Like Rodri, Kamara has a nice blend of ball playing and defensive abilities.
However, as I said, I can totally see why ten Hag would be targeting a player like Ugarte. Not so such about Fofana, though, unless it was to rotate with Mainoo, which doesn't really make sense, given that it looks like that will be Mount's role.
