Everton are set to name ex-PSV Eindhoven sporting director Marcel Brands as their director of football.
The 56-year-old Dutchman will take over from former Leicester City chief scout Steve Walsh, who took the role at Goodison Park in July 2016.
Brands has just helped PSV win the Dutch Eredivisie title.
He, along with new chief executive Denise Barrett-Baxendale, will select Everton’s new manager after the sacking of Sam Allardyce.
Allardyce departed on Wednesday after six months in charge, the day after the club announced Barrett-Baxendale had taken over from Robert Elstone, who will join the Rugby Football League.
PSV said Brands’ contract with Everton will begin on 1 June.
They tweeted their farewell to the former Feyenoord and RKC Waalwijk player, and wished him “good luck” at the Premier League club.
“I have had a great time here,” Brands said on the club’s website. “It’s really hard to let go of something that’s good, but I’m going to do that.
“It is a very difficult decision, but I think this is a good step at the right time.
“The Premier League is, of course, a great thing. It is the biggest competition in the world in all respects.”
BBC Sport understands Everton’s search for a new manager is expected to take between 10 days and a fortnight, as the club’s hierarchy look for a coach to implement an exciting style of football which will help them challenge for silverware and a top-six place next season.
It is believed former Hull City and Watford boss Marco Silva is the main candidate to succeed Allardyce.
The 40-year-old Portuguese was owner Farhad Moshiri’s first choice when he dismissed Dutchman Ronald Koeman last October.
