It does, however, give lie to the suggestion that it is City inflating transfer fees
Again that's not really true either. What both ourselves and Chelsea did was normalise what was considered pretty high, but not huge transfer fees.
Chelsea for example in 03-05 made £15-20m a normal transfer fee. Prior to that there'd been bigger ones like £30m for Ferdinand, but they were few and far between and 10m would get you a really good player. 15m+ was rare
Then Abramovic came along and spend 15 on Veron, 17 on Crespo, 17 on Makelele, 14 on Robben and 14 on Ferreira, 15 on Mutu, 18 on Duff. Suddenly good players for a top 4 side cost £15m+ as standard, everyone else had to catch up.
And we did the same with the £25m transfer fee. Pretty uncommon before 2008, but 18 months later we'd normalised that as the fee for a very good player.
In reality these are much more important to transfer inflation than the once a decade, blows everyone out of the water transfer like Neymars or Ronaldo.
My point to people who say we inflated the market would be 1) Yes, who gives a shit? and 2) You shouldn't have made us spend very big very fast by introducing FFP and making a long project get condensed into 2 summers of spending 3) Every club who we bought a player off should be thanking Abu Dhabi for their cash injection and 4) It's really only accelerating a naturally occurring process anyway.
