London - West Ham United have completed the signing of France international playmaker Dimitri Payet from Marseille on a five-year contract, the Premier League club announced on Friday.
The East London outfit said they had paid "an undisclosed eight-figure fee" for Payet, but reports in France have said that Marseille accepted an offer of 15 million euros (10.6m, $16.8m).

Payet's contract comes with the option of a further, sixth year.
"West Ham really showed that they wanted me to come. That's very important for me," Payet told West Ham's official website.
"I was also keen to sign up to a clear project. West Ham's is very interesting and matches perfectly with my ambitions."
The 28-year-old from the Indian Ocean island of Reunion won his 15th cap for France in a friendly in Albania earlier this month.
Formerly with Nantes, Saint-Etienne and Lille, he scored seven goals for Marseille last season and was the leading assist-provider in Ligue 1 with 16.
Payet becomes West Ham's third close-season signing following the captures of Spanish midfielder Pedro Obiang from Sampdoria and Ireland goalkeeper Darren Randolph from Birmingham City.
The Hammers have also appointed a new manager in the shape of Croatian Slaven Bilic, who replaces Sam Allardyce.
However, for Marseille, Payet leaving is a major blow following the earlier departures of talisman striker Andre-Pierre Gignac, Ghana star Andre Ayew and defensive stalwart Jeremy Morel under freedom of contract.
Ayew moved to the Premier League with Swansea City, while Morel joined OM's Ligue 1 rivals Lyon and Gignac made a surprise switch to Tigres of Mexico.
