I've always thought he was overrated. Same with the majority of Spurs squad.
It's why I rate Poch so highly. People think he has this great squad but only Kane and Son are near top quality, and Dembele before he left (jury is still out on Ndombele and Lo Celso depending on how they settle). Ali, Eriksen, Toby, etc, have all heavily benefited from having Poch work wonders as none of them are anywhere near top quality.
It's Fergie-eque in how Poch got the likes of Eriksen and Ali performing at the levels they once did.
