#4 Most expensive goalkeeper
This record hasn't been breached in 16 years and in the football transfer market that's a long time! The record is held by none other than arguably the greatest goalkeeper of all time - Gianluigi Buffon.
Buffon cost Juventus a massive €52m in 2001 when he moved from Parma. The second most expensive goalkeeping signing ever happened in this transfer window when Manchester City signed Ederson for €40m from Benfica. This just makes Bayern's deal for Manuel Neuer in 2011 look like daylight robbery.
I believe that there is only one goalkeeper on this planet who could make a move this summer while breaking Buffon's record in the process and that's David de Gea. There is also just one club capable of completing a coup for Manchester United's prized possession and that's Real Madrid.
This battle for De Gea has been going on since 2015 and it will be interesting to see if the final act happens this summer.
