Liverpool confirm Slot will fill place left by Klopp

However, in a departure from tradition, the Dutchman will become the club's first head coach rather than manager.

The PA news agency understands Slot has signed a three-year contract and will officially take over on June 1, subject to a work permit.

"It is certainly not an easy decision to close the door behind you at a club where you have experienced so many wonderful moments, and worked so successfully with so many wonderful people," Slot said in a departing message to Feyenoord fans on their official website.

"But as a sportsman, an opportunity to become a head coach in the Premier League, at one of the biggest clubs in the world, is difficult to ignore. I am grateful to Feyenoord for their willingness to cooperate in this transition."

Liverpool's exhaustive search - incorporating sophisticated data analysis, character and performance research, market assessment, performance evaluation and various other indicators - identified the 45-year-old as their preferred candidate several weeks ago and his desire to take the job allowed for a swift appointment.

It has been an open secret for some time, with Liverpool paying PS9.4 million ($A17.9 million) to Feyenoord, and Slot confirmed Anfield was his next destination on Friday.

Slot was attractive to owners Fenway Sports Group (FSG) as they believe he has demonstrated a reputation for over-performance with AZ Alkmaar and Feyenoord, being able to bring the best out of players and has a clear footballing identity, while also adopting an holistic and collegiate approach which fits with their ethos.

His job title of head coach means he fits into the new football structure which has had an overhaul in the last few months with two former sporting directors - Michael Edwards and Julian Ward - returning to the fold as FSG's chief executive of football and technical director respectively.

New sporting director Richard Hughes has been recruited from Bournemouth and will officially begin work on June 1.

Slot joined Feyenoord in 2021, leading them into the inaugural Europa Conference League final the following year, and to their first Eredivisie crown in six years in 2023.

"Feyenoord is the club where I was able to celebrate the first major successes in my career as a trainer and where I experienced many great matches, so I cherish those memories," Slot added.

"And as a football fan, I will certainly continue to follow the club, not least because I am convinced that a lot of great things still lie ahead in Rotterdam. I wish Feyenoord and everyone who cares about this wonderful club all the best for the future."
