After a summer of frivolous spending from the likes of Paris Saint-Germain, Barcelona and Manchester City, one question has been asked numerous times.
How much would some past legends be worth these days? If Kyle Walker and Benjamin Mendy are worth north of £50m, then what is AC Milan icon Paolo Maldini worth?
It's often very difficult to work out due to inflation and the fact that so much more money is being pumped into the game now.
But, Giffgaff have had a go at calculating some legends values statistically and the results make for some very interesting reading.
PELE (Compared to Neymar) - £351m
That's right, the legendary Brazilian would cost a truly astronomical fee, one which almost doubles that of Neymar's £198m. To be fair, by the time he was 25, he had already scored 515 career goals. Not bad.
FERENC PUSKAS (Compared to Neymar)- £258.7m
The Hungarian legend would also cost a pretty penny, moving for over £50m more than Neymar.
GEORGE BEST (Compared to Sigurdsson) - £157m
The United legend would rightly cost more than three times what Everton paid for the Icelandic midfielder.
MICHEL PLATINI (Compared to Sigurdsson) - £155m
Clearly that stats aren't too bad, as another true great warrants a price tag befitting of his brilliance. Either that or Everton overpaid by some margin. Probably a bit of both.
JOHAN CRUYFF (Compared to Lacazette) - £242m
The Dutch magician was one of the greatest and as such, his value is rated as more than four times higher than that of Lacazette. Pretty sure not many will argue that.
THIERRY HENRY (Compared to Lacazette) - £103m
Arsenal's record goal scorer is the man Lacazette is looking to emulate and if he were available to Arsene Wenger today, he'd be valued at almost double.
DIEGO MARADONA (Compared to Lukaku) - £94m
That's right, £94m, the definition of bargain, in the scheme of things. If you gave someone the question of who they'd prefer, Maradona or Lukaku, anyone who answered the latter for a cheaper price is simply wrong.
TONY ADAMS (Compared to Lindelof) - £64.1m
The Arsenal legend would command a price tag nearly double that of Man United's Swedish defender. After seeing his error against Huddersfield, it should be way more.
RIO FERDINAND (Compared to Lindelof) - £56.6m
The former United defender and BT Sport actually joined Alex Ferguson's side for £30m way back in 2002, so it's hard to believe that his value would not have shot up more.
PAOLO MALDINI (Compared to Walker) - £111m
The final one see's perhaps the finest defender ever to grace the game earn a fairly beastly valuation, one which given his brilliance, would probably be a bargain in this day and age.
