The cider is good my friend, but I think you'll win your bet...
They have never ever ever ever done anything to suggest that any of the signings they have made have been vindicated.
Naturally I stand to be wrong, but I've seen better Spurs teams do worse than people expect these lot to, but the truth is none of the players in their team, for all their hype, have ever achieved anything, with the exception of the over the hill Davids, and the brilliant Defoe, who has only achieved national respect.
Until they do, my opinion will remain.
