Roy Keane says former Manchester United teammate Ryan Giggs would be worth £2 billion in today's "mind-boggling" transfer market as clubs command massive fees for "average" players.
The Republic of Ireland assistant manager expressed his surprise at some of the figures which have been paid this summer, with Paris Saint-Germain forking out a staggering €222 million for Neymar and preparing to invest heavily once again in Monaco's Kylian Mbappe.
Keane played in Sir Alex Ferguson's all-conquering Manchester United side alongside the likes of Peter Schmeichel, Jaap Stam, David Beckham, Paul Scholes, Ryan Giggs and Ruud van Nistelrooy, as well as Real Madrid star Cristiano Ronaldo, who cost Real Madrid £80m when he left Old Trafford eight summers ago.
