The 32-year-old played under Redknapp at Tottenham and, with the Major League Soccer season over, could be available on a short-term deal similar to that which took him to Aston Villa last season.

QPR head into Saturday's fixture at Wigan bottom of the Barclays Premier League and still searching for their first league win of the season.
