The summer transfer window is not yet officially open, but the biggest teams around Europe are already hard at work closing in on their preferred transfer targets, with some signings already completed.
While plenty of clubs will be hunting around for that bargain capture, a lucky few are able to splash out serious money before getting any back in, such as Barcelona finally signing Neymar after years of speculation.
Here we take a look at the eight biggest signings of the summer window so far, with some criteria applied to give each one a grade.
First, only transfers which have been confirmed as completed are considered. Next, the reported value of the transfer is weighted against a subjective view of the quality of the player, what he has shown at his previous club and how much difference he might make to his new team.
The potential mid-to-long-term value of the signing is also accounted for, along with potential resaleability and the possibility of recuperating part of the initial outlay of the signing. Finally, the competition(s) a player is moving from and to will be taken into account before giving the final grading for the transfer overall.
