Championship Brentford have extended John Swift’s loan from Chelsea until 3 January.
The 20 year old midfielder has impressed since moving to Griffin Park on an initial one-month loan.
“He has been a very good addition to the squad,” Brentford head coach Lee Carsley told the club’s website.
“It is important he doesn’t rest on his laurels. His work-rate has been outstanding and if he wants to stay in the team he has to maintain that.”
