Queens Park Rangers have completed the signing of Monaco midfielder Axel Prohouly and free agent Joseph N'Guessan.
Prohouly, a 17-year-old French youth international, arrives at Loftus Road on a three-year deal following the expiration of his contract with the principality club.
Meanwhile 19-year-old N'Guessan joins QPR following his release from Stevenage after putting pen to paper on a one-year contract.
R's director of football Les Ferdinand told the official club site: "Both Axel and Joseph are players that we've identified with the future in mind.
"While there is much talk currently surrounding our transfer activity at first-team level, it's important that we also recruit and produce players from the levels below.
"We've publicly stated that's our aim moving forward, and we're pleased to have added both Axel and Joseph to our Elite Development Squad."
QPR's Under-21 team plays in the Professional Development League Two.
