For me what's more bizarre is that players continue to sign massive wage deals without release clauses. Surely if you're a guy with ambition to go to the top you'd knock £10k a week off your wages and have a clause in that means you could get the move?
Someone has claimed previously on here that release clauses are not binding in england, maybe that's why most don't bother. Not sure how true, but it certainly happened with Suarez, when Arsenal triggered his release clause by £1 more, and liverpool refused it anyway, and sold him to Barcelona next year for twice the release clause.
