Chelsea midfielder Deco was delighted with victory over former club Porto this week.
Deco spent seven years at Porto and helped Chelsea to their 1-0 Champions League win.
He told chelseafc.com: "[Tonight] we played well, we had some chances to score but the second half we played better and controlled the game with possession.
"All the players are fit, it's important and we have a very good coach with another system, I think a better system for these players," he analysed. "All the players are working hard which is important for us.
"The atmosphere is good, we just need to maintain the same level and continue to work and we will have the possibility to win things."
