He's not expected to be a champion and I believe we're not signing him as one
He was wanted by Conte for the qualities you already mentioned and I think that's exactly what we expect from him. Someone who will cover lots of ground, help in defense, help in attack, as well as act as a plan B for many positions in case the starter gets injured.
I like the player and his versatility. The kind of player who will not only improve the team but also allow us to create a smaller squad with the accent put on quality instead of quantity.
