Claudio Ranieri insisted the Champions League quarter-final tie is not over yet, despite seeing his Chelsea team held to a 1-1 draw by Arsenal at home.
Ranieri said: "Chelsea are strong away and I believe it is not finished yet.
"They are hypothetical champions in the league, and maybe also in the Champions League, but first they must kill us.
"It was important for us to win to regain our confidence but after this performance my players are happy. I am happy, I am very pleased."
Ranieri was disappointed to see Robert Pires' goal cancel out Eidur Gudjohnsen's strike just six minutes before but remained positive about the result.
"For 10 minutes after that we were fantastic, we had confidence and played good football without being anxious.
"We played with free minds and maybe with our football we deserved to score a second goal, but instead we conceded.
"It was great play from Arsenal and Pires scored a good goal. It was a match for us and I enjoyed it a lot."
