Chelsea youngsters Josh McEachran and Ryan Bertrand have both signed long-term deals at the club.
The England Under-21 duo have signed five and four year deals respectively after both making their first-team debuts last season.
McEachran is a graduate from the FA Youth Cup winning side of 2010, while Bertrand joined the Blues from Gillingham in 2005 and has recently applied his trade in the club's youth and reserve sides.
On signing, McEachran said: "I have wanted to do that since I was a kid, since I joined when I was eight years old. It will be good if I do but I need to keep working. This season my target is just to play more minutes. Hopefully I will play more games and keep improving."
Upon penning his four-year deal, Bertrand commented: "It's a big commitment, I see the club going in the right direction. I want to stay here, it's the reason I came here six years ago and it's refreshing to have the new manager come in. I'm looking forward to listening and learning from him.
"I can see the manager is young and hungry and wants to take the club forward so I want to be part of that and I thought it was best for me to stay. Obviously Ashley [Cole] is number one left- back but hopefully I can get a game here and there."
Both players are expected to gain more experience on Chelsea's tour of Asia this summer, where Andre Villas-Boas' side play in the Asia Trophy.
Bertrand was part of Stuart Pearce's England Under-21 squad at the European Championships, while McEachran, who made his Under-21 debut last season, played for the Under-19 squad in June.
