Most of whom already have an established LB with plenty of years ahead of them. We can offer regular football right now.
Same with Tierney at Celtic. Get one of them and a long term, first choice CB and that'd be a good summer.
Utd dont, City dont, currently, I know they have Mendy, but still, Arsenal dont, Liverpoo dont, only really Chelsea and Spurs, Sessgunno could play LW for Spurs, from the "top teams" have a good LB IMO.
