"Europe has become the unfinished business of my career," he explained.
"The game against Manchester United in Moscow is still a painful memory for the players.
"We had the cup so close but we have to forget and concentrate on reaching the final again this season.
"Chelsea were better than United in Moscow and we should never have got to penalties. We were on top in extra time and we should have finished the job.
"The team has another air about it at the moment. Scolari has connected well with the squad and that is the key for things to work well.
"The atmosphere is different to that under Avram Grant."
