QPR have tabled a bid for Nottingham Forest defender Jamaal Lascelles.
The 20-year-old centre-back, who has been monitored by several Premier League clubs, has represented England at Under-18, Under-19 and Under-20 levels.
Lascelles has made 38 first-team appearances for Forest, 34 of them coming last season, and has also had a spell on loan at Stevenage.
Harry Redknapp is keen to bring in at least one central defender this summer.
The QPR manager has agreed a deal in principle for former England and Manchester United star Rio Ferdinand, although chairman Tony Fernandes has reservations about signing the 35-year-old.
And an offer has been made for Cardiff City’s Steven Caulker, who played under Redknapp at Tottenham.
Derby County midfielder Craig Bryson is another of Redknapp’s targets, while a number of strikers are being considered as possible signings.
