that was my worry for tottenham, it was hard to single anyone out because on the face of it most of them, lamela and eriksen in particular, do look good players, but tottenham, after selling bale went on a spending spree that echoed the first seasons of man city, chelsea, psg etc as mega-money clubs.
in all those cases big name players were bought that were available and had a very poor return for the money. robinho, veron, glen johnson, milner, gameiro, pastore, menez, Jo, santa cruz, mutu, damien duff are all examples of players that went for big money (I think, not so sure about the PSG ones) and then totally under-whelmed. the upshot for those clubs was that those players boosted the profile of the club and through continued spending they were able to eventually land on real world class players, like Silva, kompany, essien or Drogba etc. but they there was usually just one or two of them for every five or six useless signings.
I couldn't have singleded out which guys would be poor but by looking at past history did sort of expect most them to turn out to be wastes of money, and tottenham don't have the spending power to keep doing the same thing every season to dig up new world class players.
in short, they're screwed.
