If Kane goes they are in real trouble, like mid table to 15th finish. Son when on song is top top class, but he blows hot and cold, Kulusevski is good without being amazing, Richarlison is good but never worth 60mil.
Kane is the stand out in that team, true world class player. Their midfield is a bunch of run of the mill physical DM's in Skipp, Bissouma, Hojbjerg, Bentancur the only player that has a bit of something about him going forward. Their defence has clowns like Sanchez and they rely far too much on Dier who is average and should really be a squad player.
The squad needs a clear out and big investment to fix the transfers of flops like Gil, Ndombele, Lo Celso and freshen the backline. But that is never going to happen under Levy/Enic. They have players that should have been moved on years ago like Sanchez, has been at Spurs for 6 years and still just as bad as when he arrived.
