Unai Emery (L): Poses with the Europa League trophy in Warsaw

West Ham are to hold talks with Sevilla manager Unai Emery in the next 48 hours over their vacant manager’s position, according to Sky sources.

Emery has won plaudits and trophies in equal measure in recent seasons, his stock further enhanced after his side retained the Europa League with victory over Dnipro last week.

The 43-year-old is also understood to be on Napoli's radar after the Serie A club lost Rafa Benitez to Real Madrid.

Last week, Hammers co-owner David Sullivan promised supporters there would be imminent signings and a 'big-name' manager.

He said: "I am dedicating every waking minute to recruiting the best available manager to drive our club forwards.

"It is a constantly changing landscape but we are being absolutely thorough in our search, by speaking to representatives of a number of managers and doing our own due diligence on each one.

"Given that, I am not expecting us to make an appointment for at least a week as we must do everything we can to get this appointment right."

Ajax boss Frank de Boer, former Hammers stalwart Slaven Bilic and Marseille coach Marcelo Bielsa are others to have been linked with the vacancy created by Sam Allardyce's departure after four years at the Boleyn Ground.
