Have a look on www.transferleague.co.uk .
I accept it isn't entirely accurate but it's good as a rough guide.
Your net spend over the last twenty years is over 167m whereas ours is about 24m.
Your spending power is light years ahead of ours and that is what we are hoping will change.
A massive percentage of that spend was in two transfer windows - Damien Comolli wasting vast sums of money in the summer of 2008, and trying to repair some of the damage the following January.
Also, some of those fees need an asterisk - the fees for Defoe, Kaboul and Crouch involved monies Pompey had yet to pay us for Defoe, Kaboul, Pedro Mendes and Noe Pamarot. In the case of Defoe, the actual money we paid for him was around £7-8m, with the rest deducted from what they owed, whilst the £12m fee quotes is wholly inaccurate - he was signed for around £8-9m, with add-ons. And, naturally, you have ignored the column that shows Spurs have made a profit on transfers - whilst West Ham have not.
