Marc Guehi hopes he can break into Frank Lampard's first-team after signing a new contract with Chelsea.
The 19-year-old defender has put pen to paper on a new deal that will run until at least 2022.
"I'm really excited and happy to sign a new contract and extend my stay at the club," he told the official Chelsea website.
"I can now focus completely on my football and try to better myself every day.
"I'll continue trying to do the best I can and make an impression when I'm playing. Having the captain's armband with the development squad gives me that extra bit of responsibility and allows me to show my leadership qualities.
"Seeing how Frank Lampard has given the younger boys chances is really inspiring for me and gives me that motivation to push even more. Players like Andreas Christensen and Fikayo Tomori have broken through as defenders in the last few seasons and that really motivates me, as well as someone like Billy Gilmour who I know very well. It's an amazing achievement for him - hopefully myself and many other players get the opportunity to play for Chelsea as well."
