Chelsea boss Roberto di Matteo knows they have a big target on their backs as defending Champions League title winners.
The Blues kickoff their defence against Juventus.
"Every opposition is going to play with extra motivation against the holders," said Di Matteo.
"So it makes our lives more difficult. Even in the Premier League, I'm sure Mark Hughes would have tried to motivate his team on Saturday by telling them they're playing the European champions.
"I'm aware no team has defended the trophy and I'm not surprised because it's such a difficult competition to win.
"To win it twice in a row has proven impossible so far, because it's so competitive.
As for Chelsea's triumph on penalties in Munich, Di Matteo added: "I have my memories and maybe when I have more time and I'm a bit older, I might watch it again. At the moment, I've other things to do. I've moved on. That's part of the past and history and I like to look forward."
