The bottom-placed R’s host United at Loftus Road on Saturday and Redknapp insists he is looking forward to the challenge.
Redknapp suggests that recent results shows a win for United will not necessarily be a formality as he looks to take something from the clash with Sir Alex Ferguson’s side.
"You can't predict results," Redknapp told the Fulham Chronicle.
"We then play Tottenham at home who've beaten everybody away and have scored in all away games - and they don't score against us."
He added: "Against Man City who are champions, we get another great point and then another at West Ham, which is a hard place to go.
"So we're just as capable of getting something against Man United as anyone else."
