The Frenchman has been a star for The Hammers so far, but he was relatively cheap.
The West Ham star was snapped up from Marseille where he had earned a reputation as the Ligue 1 assist king.
He has certainly been in great form this term. His performances have been sensational for West Ham - for whom he has already become a firm fan favourite.
His signing is one of the pieces of transfer business that has been highly praised by West Ham co-chairman David Sullivan this week.
He has been speaking to The Mirror about the transfer philosophy of West Ham, with Payet mentioned:
“We are not buying youth for youth’s sake. If you look at Payet who is 28, he is a classic example. He is at the peak of his form.
“He has been a fabulous signing. Maybe now people believe me when I say that if he were five years younger he would be a £30million player. He is the leading assist-maker in the Premier League. He wouldn’t look out of place in any of the top teams."
Payet's form has not however seen him given a long-awaited call-up to the French national team - much to the annoyance and misunderstanding of West Ham fans and their coach Slaven Bilic.
But if Sullivan's star buy continues to perform in the way he has been in the early parts of the season there is little doubt that his Les Bleus opportunity will emerge.
