well in that case, manchester uinted has also paid around 17 million each for anderson, hargreaves, nani and carrick and all these players were signed in 2006-2007.
Carrick, Nani and Hargreaves were worth the amount we paid. I dont expect you to be watching United matches, but Carrick has been top class in many seasons since he signed. Nani has been exceptional and has always been in the top of the charts for assists. Hargreaves(although his presence in the 07-08 campaign was immense, with vital perfromances against Arsenal and in UCL KO phase) case is a sad one, if not for the injury, him along with Fletchinho(suspended for the final for a 100% legit tackle on Fabregas) would've made the diff against the Barca in 08-09
