Goals from Ferran Torres, Ilkay Gundogan and Raheem Sterling sealed the win, capping a fine all-round performance from a dominant City side.
And Pep Guardiola was full of praise for his side afterwards.
“Our application is exceptional from the first day I have been in this club,” he said.
“Sometimes the opponents are better than us, that is life.
“I know when you win you are a master and when you lose you are a disaster.
“It is important to start the Champions League with two victories because we are so close to being in the last 16. But still, it is the beginning. We are still improving.
“I saw the mentality from the first five minutes, the way we played. We were incredibly patient to wait for the right moment to score and not concede counter attacks.
“For 15-20 mins they were better. We defended well in the box. In general it was a good performance because in Europe I know how demanding and difficult it is.”
