I don't think people remember the scale of what Poch walked into at Spurs. Adebayor stinking the place out on big wages, big money signings in Soldado, Lamela, Paulinho who were massive flops. They were in an awful state after AVB had wasted their resources. The atmosphere around the club was rotten. No resources left, but the club needed a total overhaul. It was a very tough job for anyone.
People see the players already there and think he arrived with them at that level. Eriksen was promising, but Lloris, Vertonghen, Walker, Rose were all part of the side shipping 51 goals the previous season (11th best defensive record). They conceded 27 goals in 8 matches to the top four alone that season, scoring just 2 goals vs. them. They also only scored 55 goals overall. 7th highest behind Everton (61) & us in 5th (64). That's our 13/14 season under Moyes, enough said.
We have a lot of similarities to Spurs when Poch first joined them.
A broken, soft team, with overpaid pampered 'stars'. The upside was, Poch inherited a young team, but he still had a lot of hard work to do to guide them to their full potential over the years. Without quality coaching and guidance, there's not a chance they would have developed the way they did.
Kane acknowledged this point himself that he would never have developed the way he had, if he was still around the dysfunctional set-up before Pochettino.
