QPR appear to be the busiest Barclays Premier League club as the transfer deadline approaches, confirming the signing of South Korea full-back Yun Suk-young on a three-and-a-half year contract and closing in on defender Christopher Samba.
Yun, who was part of the South Korea squad that won bronze at the London Olympic last summer, joins the west London club from K-League side Chunnam Dragons for an undisclosed fee.
The 22-year-old has been granted a work permit and will be eligible to play for the Hoops when he is granted a visa.
Yun joins fellow January acquisitions Loic Remy and Tal Ben Haim at Loftus Road, where he will also link up with countryman Park Ji-sung.
QPR boss Harry Redknapp has also made a move to sign Anzhi Makhachkala defender Samba after the Rs triggered the release clause in his contract.
The Congolese defender's arrival would go some way to bolstering a defence that is short on options after QPR loaned Anton Ferdinand to Bursaspor earlier this week with Ryan Nelsen leaving to become head coach of Toronto FC.
Redknapp said: "We are struggling a bit. We are desperately short. The chairman (Tony Fernandes) is dealing with it (the Samba deal) I don't know where we are at with it.
"He (Fernandes) asked me about a week ago if I would be interested if he could get me Samba and I said, 'Of course, he is a fantastic competitor'."
Peter Crouch and Etienne Capoue are among those also believed to be on QPR's radar ahead of Thursday's deadline while it is believed the club have given Alejandro Faurlin permission to speak to Palermo over a loan move.
