"We have a lot of world-class players in front of me at Chelsea so it is a question of being patient," said Mancienne.
"I would love to be playing more games, but I have had a lot of good experiences. I was on the bench for the Champions League semi-final, so I did gain a lot of experience from that.
"This is a good tournament to show Ancelotti what I can do. I would want to play well in this tournament, even if there hadn't been a new manager coming in at Chelsea, but obviously having a new boss, you have the chance to impress, so it is important to me."
Mancienne, 21, who played four league games for Chelsea in the last two months of the season, said: "You just have to be patient and bide your time because I don't think you can break in at a young age at a team such as Chelsea. I just want to take it as it comes over the next year."
