I thought Lamela was our transfer record when we signed him? £30 million was a lot of money back then. It just didn't seem it because of the astronomical amount we got for Bale (who lets face it is worth more than 3 times of Lamela in anyone's money).
Indeed it was under Sherwood, with Sherwood taking over a team who had finished 5th under AVB the season before (with Superman Bale) but having slipped to 7th the season after at the point that Sherwood took over in December.
We were not a top 4 team when Pochettino took us over.
The squad he inherited from AVB/Sherwood was:
Gomes, Friedel, Lloris
Walker, Rose, Kaboul, Vertonghen, Dawson, Chiriches, Naughton, Fryers
Lennon, Paulinho, Lamela, Capoue, Townsend, Dembele, Chadli, Sigurdsson, Eriksen, Sandro, Bentaleb
Soldado, Adebayor, Kane
Us establishing ourselves as a top 4 team was a result of some good transfers (Alderweireld, Dier, Wanyama, Son, Ali) establishing an excellent team spirit and some very good coaching (Walker, Rose, Kane, Dembele, Eriksen)
Poch took a 5th/6th best team in the PL, spent less than all of those who had finished above him and still turned it into a top four team.
