Herita Ilunga is set to turn his loan move at West Ham into a permanent deal.
The Congo international, who is currently on a season-long loan from Toulouse, has impressed at Upton Park since his arrival in the summer.
The 26-year-old has established himself as a key performer in Gianfranco Zola's side and they are set to reward him with a four-year deal.
llunga's performances have seen him linked with a move to Liverpool, but West Ham have moved quickly to secure his permanent signature.
"We really wanted to keep Ilunga," Zola told The Sun.
"I must say he has done fantastically well."
