In case you ever want to know for how much a player has been sold, when the transfer occured and which clubs were involved, I have found this preety cool site which has most of what you are likely to be looking for.

Just thought I would share.
No, I am not related in any way, shape or form to that site, I just stumbled across it while doing my daily transfer rumours.
Cue the Nani jokes...
