I'm not so sure Joao Mario is what Conte is looking for, Carvalho definitely not, he's a dm, he can't exactly do what a real b2b would be able to do (although I would love to sign him, I'm a fan). I myself suggested Kante as a b2b, even though I think he'd be more suited to be the dm, and that is already stretching it, but if that is the path we have to follow, then so be it; Gueye could be a good shout, but then take Kante and slap it as b2b, think he could give us more quality.
Yes Azpi goes nowhere, I agree. Iva as a cover, I agree. Baba? Meh, it's either him or Kenedy as a backup LB, I'd prefer Kenedy. We need a proper starter either on the left or the right.
