Transfer talk: January 7 - Nelsen set for MLS move, Michu sale ruled out
After watching his side gain a fortunate 1-1 draw against West Bromwich Albion in front of just 8,984 fans at Loftus Road in the FA Cup third round, the manager of the Premier League's bottom club revealed he faces losing the key defender and club vice-captain Ryan Nelsen in the January transfer window.
Nelsen, 35, has been linked with a move to Major League Soccer in the United States, potentially with his former club DC United, and Redknapp believes if he goes it would be a blow to QPR's survival hopes.
Redknapp said: "Nelsen is very important to us, a fantastic leader, a top player. But he has been offered a job in America and I think there is every chance he might want to go. He wants to be a manager and it is a chance for him to manage a club.
"He has been fantastic. I took him to Tottenham last year from Blackburn. He's one of the best pros I've ever met in my life, a fantastic player, a great trainer. He is a massive part of our team. To lose him would be a massive blow for us."
Nelsen has six months remaining of a one-year deal but Redknapp said: "I'll have to speak to the owner to see what the situation is with that. We'll try [to keep him] but it is difficult."

But with reported interest from Russian clubs Zenit St Petersburg and Anzhi Makhachkhala, Laudrup emphasised Michu would be remaining at the Liberty Stadium.
"There is no way he will leave," said Laudrup. "It is absolutely out of the question.
"One reason is because it is so difficult to get someone in right now, and the second is that he is happy here and doesn't want to leave.
"Newcastle have just lost their top scorer midseason and that is obviously very bad. especially because it is not easy to find a guy who scores goals like him."
Wolfsburg have completed a deal to sign Ivan Perisic from Bundesliga rivals Borussia Dortmund, pending a medical.

Perisic will sign for Wolfsburg upon successfully passing his medical today.

Jose Anigo, sporting director at Marseille, admits his side could sell striker Loic Remy this month.
The 26-year-old has been hampered by injuries this season, limiting him to just one goal, but is reportedly on Newcastle's radar as they seek a replacement for Demba Ba.
"Some English clubs are looking at our players and have not yet come knocking on the door," Anigo said.
"It will come. The only window of opportunity at the moment is for Loic Remy, if a big club comes for him and he is interested. We will see, but otherwise no one will go.
"His succession of injuries has hampered him, and saw him miss the Euros. But I think he is back. I can see in training there is a renewed confidence.
"But if he left, we still have a strong attack with (Andre-Pierre) Gignac and Jordan Ayew. We are well armed."
