Chelsea boss Roberto di Matteo says they cannot rely on last season's achievements.
Di Matteo says their European and FA Cup success is now for the history books.
"The pressure is always there, whether you have won or not. It's a pressure job," Di Matteo tells Chelsea magazine.
"I think we are all happy with what we achieved last season, but we have to understand that is part of the past now.
"Now, we have to look forward - and there is a lot of excitement. We have a lot of targets and objectives to achieve this season, competitions that are very difficult to qualify for, like the European Super Cup and the World Club Championship.
"It takes a long time to reach those competitions and it's hard to get there, so I'm looking forward to this season with a lot of excitement."
