Josh McEachran says it was time for him "to get out" of Chelsea after signing for Championship side Brentford.
The 22-year-old midfielder only made 22 appearances for the Premier League club following his senior debut in the Champions League in 2010.
Most of those outings came in 2010-11, but McEachran then had a series of loan spells away from Stamford Bridge.
He told BBC London 94.9: "I was at Chelsea for 15 years. I wanted a fresh start and to start playing regularly."
Brentford paid an undisclosed fee, reported to be £750,000, for McEachran, who has agreed a four-year deal at Griffin Park.
The former England Under-21 international has spent time on loan at Swansea, Middlesbrough, Watford, Wigan and Vitesse Arnhem but says he now "feels a lot more settled" having joined the Bees.
"I have signed for four years and can just concentrate on my football now," he continued.
"It gives me stability and my main aims are to stay fit and play as many games for Brentford as I can. Now is the time for me to push on."
McEachran was 17 when he made his bow for Chelsea as a substitute in their victory over MSK Zilina in September 2010.
He featured regularly from the bench that season under then-boss Carlo Ancelotti, but his last appearance for the Blues was in January 2012, when Andre Villas Boas was in charge.
However, McEachran is not bitter about his lack of first-team opportunities in his last three years at the club.
"I'm not saying I should have got more of a chance because it's down to the manager who plays. I will not point the finger at anyone and say it is anyone's fault," he said.
"I have been in and around the first team since I was 17, seen a lot of managers come and go and seen world-class players training. They have helped me a lot and I can only take positives from it.
"The Chelsea badge has been taken off me now, so there is not as much pressure, as Chelsea are one of the biggest clubs in the world.
"The expectations are big here at Brentford, but I am excited to play football."
