Nathan Ake hopes to prove himself to Chelsea boss Jose Mourinho in preseason.
The young Dutchman made his Premier League debut towards the end of last season and has hopes of making the first team squad.
He told the club official page: “In these friendly games, all the young players are trying to deliver a good performance and impress the manager.
“If we do, we will be next season hopefully included in the squad.
“I work hard every day, the games that are yet to come are very important and I will do my best.”
