Meh. It's not really Spurs' fault that Southampton got into a financial mess, so much so that they had to waive their sell on clause for a pittance.
Absolutely. Spurs have done absolutely nothing wrong. They could even maintain that they were doing Saints a big favour, letting them realise that potential money into some hard cash when they really needed it.
I doubt any Saints fans cried for us, when we did EXACTLY the same thing, regards Gareth Barry's sell-on clause, at Villa.
