Newly-appointed Queens Park Rangers manager Harry Redknapp describes his latest role as a "big challenge" as he takes control of a club that are bottom of the Premier League.

The former Tottenham and Portsmouth boss faces his first test against fellow strugglers Sunderland on Tuesday and says the players will need to "up their performance level".

Redknapp doesn't rule out a move for former Manchester United midfielder David Beckham, who has been linked with Loftus Road, describing Beckham as a "top professional".
