6. Barcelona – £336.4m
Last summer the Catalan giants shelled out around £68m on Neymar and quickly followed that up by bagging Luis Suarez for £75m. This summer they also made additions in the shape of Ivan Rakitic, Thomas Vermaelen and Jeremy Mathieu, all for pricey fees. When adding these names to previous signings like Cesc Fabregas and Alexis Sanchez then their numbers rise significantly.
