I'm assuming Pogba will go, so SMS would be a great replacement.
Ndidi as a more defensive CM i midfield would really improve the team.
Koulibaly as a world class centreback partner for Maguire would really sure up the defence for a couple of seasons.
We should probably get a better leftback than Shaw, I don't mind him but... If we replace him it should be such an improvement as Telles.
Most importantly is that we get Sancho. Young, english, fast and really talented, Sancho would be PERFECT to cover up the hole in the squad that is RW.
