I agree with most of that and like you and Steff ( and I suspect all Spurs fans) we are all depressed by what we see in our club right now - especially after we had such a great recent ride. However, to blame ENIC / Levy for everything would be entirely wrong.
Poch had five and a half years here. 26 players were bought under his tenureship. Virtually all were flops. Only Winks graduated from our academy. Hoped for internal talent like Edwards, Onyama, Pritchard, Bentaleb, CCV, KWP etc didn't kick on. His " full back whispering" didn't work with Aurier, KWP, Foyth and had stopped working with Rose and Trippier. Wanyama, Dier, Sanchez, Dele really regressed under him - and they don't have the excuse of being too old - like Toby and Jan. Where exactly was Poch's supposed excellence in working with youth and developing players? He left us with a totally unbalanced and decaying squad.
