The Blues managed to stop Barca from scoring in the goalless draw at the Nou Campwith a terrific defensive display last night.
But midfielder Essien says Guus Hiddink's side will be more confident at home and is backing his team-mate Didier Drogba to score after the Ivory Coast striker missed their best chance.
Drogba fastened on to a loose ball following a poor Rafael Marquezbackpass but his shot was well saved by Victor Valdes and then theBarca keeper kept out the rebound.
'We really frustrated them, we have not played our attacking cards yet.Hopefully we will be much better to test them at the Bridge,' Essientold skysports.com.
"We are a confident team at home, we will create more and need to gofor it a bit because to qualify we need to win and score more than them.
'Didier (Drogba) was unlucky with his chances but I think he will redeem himself if there is another chance at the Bridge.'
