Brentford have completed the signing of Chelsea midfielder Josh McEachran on a four-year deal for an undisclosed fee, understood to be £750,000.
The 22-year-old played 22 times for the Blues after his senior debut in 2010.
He spent 2014-15 on loan at Dutch club Vitesse Arnhem after previous spells at Swansea, Middlesbrough and Watford.
"Josh is a versatile midfield player who can play in a holding role and as a playmaker," head coach Marinus Dijkhuizen told the club website.
"Although he played at Vitesse last season, he has good experience of English football and will be able to fit into our playing style very quickly."
