Arjen Robben is gunning for revenge against Liverpool in the UEFA Champions League and believes Real Madrid need to secure at least a two-goal head start.
Robben was a member of the Chelsea side which lost a semi-final against Rafa Benitez's men in 2005 before also crashing out on penalties at Anfield in 2007.
And the Dutchman has added incentive to sink the Reds after seeing his spot-kick, Chelsea's opener, saved by Jose Reina in the shoot-out setback two years ago.
"I want to beat them because I have lost against them in two semi-finals and Reina saved my penalty," the winger said in the Daily Mail. "I want a chance to take another against him and score."
However, after witnessing Liverpool's strength on home soil in the past, Robben - who left Chelsea for Real in 2007 - has warned his current club they will need a first-leg advantage.
Robben feels that Real will need a safety net at the Bernabeu on Wednesday ahead of their trip to Merseyside on 10th March.
"They are very strong," he added. "The coach is tactically excellent. The most important thing is to score at the Bernabeu.
"We have to beat them by more than two goals at home because the second leg at Anfield is going to be very tough."
