Crystal Palace have reached a deal with Arsenal for Albert Sambi Lokonga.
The midfielder will sign on loan with the fellow London club to the end of the season.
The 23-year-old has struggled for regular game time at the Emirates Stadium this term.
Lokonga was likely to see his game time further reduced by the signing of Jorginho.
Chairman Steve Parish said in a statement: I would like to welcome Sambi to south London, and am pleased he has chosen to join Patrick's squad for the rest of the season, after making an impressive start to life in English football. He has been on our radar for several years since his emergence at Anderlecht, and we very much look forward to his contribution as we push to climb the table".
Lokonga added: I'm really excited I can't wait to get started. I'm really happy to join Crystal Palace. I want to go as far as possible with the team. I will try to push for me and the team to do the maximum to reach the top."
