Ranieri believes his side, despite conceding a crucial away goal, are still in contention.
"Chelsea are strong away and it is not finished yet," he said.
"This season Arsenal are in another world but first they must kill us. It was important for us to win but after this performance I am happy." Wayne Bridge admitted there was a feeling of "disappointment" among the Chelsea players after they lost the lead so quickly. "At least we didn't lose," he said. "Now we have to go there and make sure we score."
Thierry Henry urged caution from his team-mates despite Arsenal now appearing to hold the advantage. "We are not in the semifinal yet," he said. "We will only see if the away goal is important at the end of the second leg."
