"The mood wasn't downbeat in the dressing room after the game. It's still game on. If we score first at Anfield, we could be in for a very good second leg," said the Liverpool skipper.
"I think Chelsea were happy with the result, but I think they will still show us a lot of respect in the second leg. They know the tie isn't over yet and they've witnessed the atmosphere at Anfield before. They know that we're capable of beating them at Anfield - as we proved in the Premiership earlier this year.
"It's only half-time. We would have liked a better scoreline going back to Anfield but we're one down and we'll get on with it. We'll approach the game knowing that we need to score the first goal and we'll be ready for Tuesday night.
"We're confident we can hurt them a lot more at our place with the crowd behind us. We'll raise the tempo and the first 20 minutes will be really interesting next week. If any supporters can raise the roof, it's our supporters, so I think we could be in store for another memorable European night."
