"We are disappointed but we are ready for next week. People are talking about us not scoring at Stamford Bridge for a long time but you could look at the positive of us scoring in every Champions League away game this season," he told liverpoolfc.tv.
"We scored in Milan, we scored at the Emirates. We know we can score next week.
"We controlled the game until the 90th minute but you have to be focused all game long. It was really disappointing, as was the fact we didn't score more than one goal.
"But, you know, it's two games you have to play. At the end of the game maybe they were thinking they were already in the final but I am sure that's not the case.
"We know what we can do. It will be more difficult but we have a strong belief we can reach the final. A 1-0 scoreline would have been excellent but for me it's still 50:50.
"We know we were better than them. We created more chances but sometimes football is like that."
