I do think Spurs are on their way to having a really, really, really good first XI.
GK looks good, despite that piss poor flap there, the fullbacks and two central defenders look top tier. I’d imagine their central midfield will be looked at next but Bentancur, Maddison, Hoijberg, Bissouma and Sarr are really good options, whilst Richarlison, Johnson and Kulusevski are decent wide options. Son is a superstar.
As they start to improve that first XI, if they can keep the likes of Kulusevski, Johnson, Bissouma etc as squad players then they quietly have the makings of a brilliant squad.
It’s a lot of pressure on that manager to see what he can do with that squad. If they get CL you’d imagine they’d continue to invest within their limits.
