It the 100,000 were his reasons then it would have made no difference where he went, that it was the chavs that first made aware of his earning potential was the factor. Perhaps he should have just come out and said "I want to go and play for a club that will pay me more than Tottenham do".
As you say - he should have thought of that before signing his new contract and saying "I am happy at Spurs and believe that with them I will fulfil all of by ambitions".
