#3. Trevor Bayliss, England (2015-2019)
England Cricket was trapped under the shallow of darkness after their group stage exit in the 2015 World Cup. Trevor Bayliss then came into the picture and transformed the entire squad and brought the best out of players like Joe Root, Ben Stokes, Jos Buttler and Jason Roy. Under Trevor’s guidance, England finished as the runners-up of the 2016 T20 World Cup and went on to win their maiden ICC World Cup Title in 2019. Bayliss also developed England’s Test team.
