Levy crashes the train to keep the overall wage bill low.
When a player like Carrick, Berbatov, Modric or Bale emerged from the smeg, and stepped up a level while playing with a cock on his chest, Levy and ENIC never really put up much of a fight, in terms of making vastly improved wage offers to the aforementioned quartet, in the hope that they would stay at Spurs and Spurs could build on their quality. Levy realised that if he improved the terms for one player he may be expected to pay others more too.
Levy always opted to avoid increasing the overall wage bill, sell Tottenham's top performing players when they reached this tipping point, and re-invest the received ransom from the buying club into another spread bet of players, from European or English clubs of lower stature than Spurs, who were as easy for Levy and ENIC to exploit, as Spurs were from the perspective of a Manchester United or a Real Madrid.
Levy loved these hostage situations, regarding star players, and would rather sack a manager who objected to his best players being sold from under him, regardless of their achievements, to achieve the desired outcome of an overall low wage bill, low supporter expectation and a general acceptance that Spurs should 'know their place'.
Levy crashed Poch's train when he gave Lloris, Kane, Son and Dele huge pay rises, that were disproportionate to their team mates' remuneration, to protect his investment and maybe sell them at a later date.
The morale of the rest of the under payed players, such as; Toby, Jan, Rose, Eriksen, Dembele and Wanyama collapsed as they lost interest, left the club, ran down their contracts or a combination of all these things.
To remove ENIC it will require the skill and ruthlessness that Levy has demonstrated for over 20 years.
I can't see it ever happening now.
That ship sailed when they knocked down WHL.
ENIC are here until ENIC don't want to be here.
