QPR have signed France youth international Axel Prohouly and former Stevenage forward Joseph N’Guessan.
Midfielder Prohouly, 17, was a free agent after his youth deal at Monaco expired and has signed a three-year contract at Loftus Road.
N’Guessan [pictured] has signed a one-year deal. He was released by Stevenage this summer, having made nine first-team appearances for the League Two club, scoring once.
Last season the 19-year-old was loaned to non-League sides Aldershot Town and St Albans City.
Both players will initially play for QPR’s Under-21 side.
