QPR are keen for Massimo Luongo and Ryan Manning to sign new contracts at Loftus Road.
West London Sport report that Rangers have been in contract talks with Alex Smithies and Darnell Furlong and also want Luongo and Manning to sign improved deals.
Australian midfielder Luongo (pictured) moved to west London from Swindon Town along with Ben Gladwin in the summer of 2015.
The 24-year-old has impressed for the R’s this season, while Irish youngster Manning, 20, has played in the last three league matches.
Manning was handed a surprise debut for the recent win at Wolves and set up the winning goal in Friday’s victory at Reading.
Goalkeeper Smithies, 26, has been superb since arriving from Huddersfield Town last year and his form this season has led to him being linked with Aston Villa.
Like Luongo, Smithies is currently under contract until the summer of 2018.
Furlong’s contract with the club expires at the end of the season and QPR are looking to secure his future.
The 21-year-old right-back was recently recalled from a season-long loan at Swindon.
Furlong made his Championship debut in the 1-0 win against Reading after coming in for James Perch, who was ruled out because of illness.
