West Ham United have completed the signing of France international Dimitri Payet, the club have confirmed.

Payet, 28, joins the Hammers for 'an undisclosed eight-figure fee' and has signed a five-year contract with the option to extend that to six.

He becomes the club's third signing of the summer transfer window following the arrivals of Spanish midfielder Pedro Obiang and Republic of Ireland goalkeeper Darren Randolph.

Speaking to the club's website, Payet revealed the determination of West Ham's co-owners David Sullivan and David Gold and the role of recently appointed manager Slaven Bilic was key to his decision to make the move to the Premier League.

"West Ham really showed me that they wanted me to come, both the joint-chairmen and the manager," Poyet told whufc.com. "That's very important for me. I was also keen to sign up to a clear project. West Ham's is very interesting and matches perfectly with my ambitions.

"Firstly, I spoke with the manager, who really wished for me to come here and had been watching me a lot. He made it clear that he wanted me to sign and that too was important in my choice."

Payet added the club's promise to play an attacking brand of football also aided his decision.

"I'm an attacking footballer so for sure I like attacking football and that they're counting on me to help achieve that gives me a sense of responsibility. The fact that I'm here is also down to that.

"I'm very happy to be here. It's true that it's taken a little while but that's normal, negotiations are like that. But now that it's done, I'm very happy."
