West Ham United boss Sam Allardyce is delighted with their capture of Momo Diame.
Diame has agreed a three-year deal with the Hammers, which will be rubberstamped on July 1.
"His is potential is really good and he's ready to go and compete in the first team straight away as he's had three years in the Premier League already," Allardyce told the club's official website.
"He's 25 and can only get better and I hope he can go on to prove that to me and all of the West Ham United fans.
"He will be a very exciting addition to the squad."
