Arsenal defender Johan Djourou is confident silencing Barcelona star Lionel Messi tonight.
The Swiss defender, 24, was outstanding in the Gunners' 2-1 first-leg win.
But many of his team-mates still have bitter memories of the last time they faced Argentinian ace Messi at the Nou Camp when he scored all four goals to knock them out.
Djourou said: "I think we made it hard for him at the Emirates. He always had people next to him and you need to keep them under pressure.
"We have to show the same focus and communication at the back - we learned from last year and showed a lot of character.
"We just want this so much and this team can achieve something great. Even if we are down we will continue fighting to the final whistle."
