Queens Park Rangers manager Harry Redknapp believes that his team need to put in a "top performance" in order to "shock" Chelsea at Stamford Bridge on Saturday.

In the 2012-13 campaign, the R's pulled off a 1-0 triumph, but the team now face a Chelsea side who have a four-point lead at the top of the Premier League table.

"We pulled off a shock last time, let's hope we can pull off another this weekend," Redknapp told reporters. "We'll need a top performance, they're the best team in the country, the team to beat this season for sure, but we'll give it a go."

QPR are 16 points behind Jose Mourinho's Chelsea side.
