I am REALLY big on your last point. The time aspect. IMO we would have progressed so much more if we had not sunk time into Defoe, Fryers, Townsend, Lennon, Naughton, Rose etc. While Lamela, Capoue, Ade, BAE etc rotted away. We should have gone back 3 and cut out wingplay WAAAAAAAAY earlier. We had Vert on the left, Chadli in the middle, Walker running around like an idiot, Soldado on his own, terrible crosses to nobody, Dembele in a sad withdrawn role etc etc.
We lost so much time this season with TERRIBLE formations, high lines which almost ruined the careers of solid players like Jan, Walker etc. This season is IMO the most wasteful thing I have ever witnessed. NOBODY got better an ANY aspect of their game. If anything, most players have gone backwards.
I'll never forgive AVB for doing what he did to the crowd and team. Like LLoris just said, it's difficult to see how we can do any worse next season. I can't be angry and Sherwood because as clueless as he is, at least he has got us scoring and seems to have a clue about youth.
