He’s class, we would have to change our system for him, but would be worth it . Don’t get me wrong he would be difficult to buy, especially witt Lyon selling Fekir and Ndombele.
Aouar is talented, but I don't see him as a defensive oriented midfielder despite his tackling stats being okay and playing more central or left for Lyon - if we are signing Gomes, keeping Siggy, where would he play? He'll be super expensive and honestly, while his talent with the ball is great, his decision making is suspect. He's also out of control often as a player. He could turn out to be AMAZING or could be a bit of a bust.
So to me, we need a CM/DM type, Ibrahim Sangare is ideal to me (and Zat I think). There are others, too, but I think that type of player is a better fit for what we need.
That being said, if they sell Fakir, they won't lose a beat. I hope LFC buy him, because he's supremely overrated IMO much like Naby Keita. Ndombele is really talented and would be a much better fit, but he's going to be CRAZY expensive. Tousart is a good player, too, and the Lyon academy is amazing, so my guess is they'll still be decent even if they sell a couple of guys in the midfield.
