I think we need a new defender in anyway. Per's finished as much as I love him, and Gabriel is an absolute calamity- both should make way in summer. Bring Chamber's back or loan him again I'm not really fussed but I'd absolutely love us to go and buy another defender this summer.
Virgil van Dijk would be a dream. Just get a nice EPL proven defender in that knows the league, get him settled early and approach the opening game of the season with players that actually have the ability to fucking win the game.
