Gerard Houllier, a Frenchman who won three titles in one season as coach of English club Liverpool, has died. He was 73. Liverpool announced the death on Twitter on Monday. French sports daily L’Equipe said Houllier died following heart surgery in France. “We are mourning the passing of our treble-winning manager, Gerard Houllier," Liverpool wrote on Twitter. “The thoughts of everyone at Liverpool Football Club are with Gerard’s family and many friends. Rest in peace, Gerard Houllier 1947-2020." His tenure at Liverpool was far more successful, leading the Reds to the FA Cup, League Cup and UEFA Cup treble in 2001. He is one of only three managers - along with Alex Ferguson and Pep Guardiola - to have won three trophies with an English club in the same season.
