I think asking us to sign another winger as well as Tierney, a CB & a RB is asking too much of our resources this window. That said I can see us trying to get a 2 for 1 deal with a CB who can also play as RB, but who has some pace to get up and down unlike Chambers who lacks the pace to do so.
If we don't sign a LW we're looking at PEA on the flank, but with Cabellos we should be quicker in transition to enable both PEA and Pepe to get on the ball early to exploit their pace.
