Brentford's head of recruitment Andy Scott has left the club to become Watford's new technical director.
The former Bees manager, who lifted the League Two title in 2009, will now oversee operations at Vicarage Road.
And the west London club are going to take the opportunity to review how they do business and see where they can improve.
Phil Giles told the Brentford official website: "I'd like to thank Andy for his hard work over the last few years as part of our recruitment team. I believe we have made some good signings in recent transfer windows and Andy has played a strong part in that.
“As always, when a member of staff moves on it provides us with an opportunity to review how we do things and hopefully make the off-pitch team stronger in the process. We will take our time to consider how best to replace Andy. In the meantime, we will share his responsibilities among the remaining staff members and continue as usual.
“On behalf of everyone at the club, I wish Andy well in his new role at Watford."
This marks the end of Scott's third spell and fourth role at Griffin Park having been a player when the club won the old Division Three (now League Two) title in 1999 as part of a four year stint between 1997 and 2001.
His playing career was ended when a heart defect was discovered and he moved into coaching at Leyton Orient.
He returned to Griffin Park in 2007 as Terry Butcher's assistant manager before being parachuted into the manager's role in December that year.
After guiding the club to the League Two title and a mid-table finish in League One the following year, he was sacked after a string of poor performances and results.
Scott was back at Brentford in 2016 as chief scout, which later became head of recruitment in a restructure, and oversaw the signings of Ollie Watkins, Neal Maupay and others.
