In our back 4, if Laporte leaves, Gomez can't play for us, and Lewis is going to be a midfielder, then we have:
Ake, Dias, Stones, Akanji, and Walker.
That's 5 players for 4 spots, we DEFINITELY need another Defender.
I would argue that Walker, Akanji and Stones can play the RB role.
Dias and Stones can play CB, with almost anybody able to rotate with Dias. Stones role is much harder to replicate, which is why I would have liked having Rice. My definite first choice for squad depth.
And Ake, and lately Akanji can play LB.
LB is the position we need to buy.
The only other top LB's (obviously defensive ones) I can think of are Gvardiol and Bastoni.
Levi Colwill is a massive prospect, and given 5 in 4 spots, having a huge prospect like Levi is probably worth gambling on. Highly doubt Chelsea would be dumb enough to sell him to us, but he'd be my first choice, and I'd test them with like a 50m offer.
But beyond that, there's nobody else, the Gvardiol links make alot of sense for future planning, those CBs are getting up there in age.
