Michael Owen, Steven Gerrard and Jamie Carragher led the tributes to former Liverpool manager Gerard Houllier, who has died at the age of 73.
The Frenchman, who also managed Aston Villa later in his career, guided the Reds to an FA Cup, League Cup and UEFA Cup treble in 2001, the highlight of his six-year spell in charge.
Houllier also managed Paris St Germain, Lyon and the France national team during his career.
A post from Villa read: “All at Aston Villa are deeply saddened to learn of the passing of Gerard Houllier, our manager during the 2010/11 season.
“Our thoughts are with Gerard’s loved ones at this incredibly difficult time.”
Houllier’s career was marked by several successes, including the 1986 French Division 1 title with PSG and Ligue 1 titles with Lyon in 2006 and 2007, but the tributes paid on Monday were also testament to his popularity as an individual.
Phil Thompson, who worked alongside Houllier as part of his backroom staff at Liverpool, tweeted to say: “Absolutely devastated and heartbroken at the sad news of the passing of Gerard.
“French football is losing one of its greatest technicians, and the French federation one of its most loyal servants. Gerard Houllier has distinguished himself at all levels of football.
“In the amateur world as a player and then as a coach, in the professional world as a coach of renowned clubs, in the federation as national technical director and coach of the France team.
“Beyond his unanimously recognised technical qualities, Gerard Houllier was a great teacher, open-minded, warm, accessible, deeply human.
“French football owes him a lot. On behalf of the federation, I send our heartfelt thoughts and condolences to his family and loved ones.”
League Managers Association chairman Howard Wilkinson said: “As a coach and a manager, Gerard’s record speaks for itself.
“As a gentleman, Gerard was open, thoughtful and accommodating, and he will be very sadly missed.”
