Deco wants to bring the Champions League trophy to Chelsea.
Deco has already won the Champions League twice - once with Porto and again with Barcelona - and with Chelsea now sitting on top of Group A, he is gunning to make it a hat-trick and become only the second player to win with a third different club.
"I think about it because I also know that the Champions League is the most important trophy that Chelsea have never won," said Deco.
"It would be important for the club to win it and I also have the opportunity to win the competition again. This is a great challenge for me.
"To win it with Porto was not a surprise for me because we had a great team.
