Goalkeeper Thomas Strakosha has joined AEK Athens on a free transfer.
Strakosha, 29, joined Brentford from Lazio in 2022 and has made six appearances.
The Albania international has been named on the bench on 50 occasions for the Bees but has left to play first-team football.
Director of football Phil Giles said: "Like any good player, he will have wanted to play a lot more games. Being a substitute goalkeeper on a regular basis is arguably one of the toughest roles in football.
"We recognise this and therefore we are happy for Thomas to now leave to get back to starting games every week, which I’m sure he will do with AEK."
