Since Manchester United couldn't have a good performance so far during the last season now they want to improve the team and especially the midfielders, that's why they decided to stop working with Casemiro and McTominay while these two players are both key players, and effective for Manchester united but they won't stop working with both players and hire some other players instead and they think Manuel Ugarte but this player too expensive and PSG asked 65 million euros for him that's why Manchester United thinks about Sander Berge the player Burnley.
There is still no clarity about Manuel Ugarte, while Man United must quickly get a new player in the defensive midfielder position because their season will start soon. If indeed they can't sign Manuel Ugarte, then Sander Berge could be an option for them. I think if Sander Berge is given the opportunity to play in a big team, he could be a very tough midfielder because as far as I know, he has ability to read opponent's movements and breaking up opposition attacks.
But now the problem is, that Burnley seems to want to take advantage of Man United's situation and will give a high asking price for Sander Berge. While Man United probably won't want to pay that much because Sander Berge is not their main target.
