Martin O'Neill, a former European Cup winner as a player with Nottingham Forest, took charge of the club in June 2000.[49] O'Neill's first Old Firm game, in late August 2000, ended in a 6–2 victory for Celtic.[50] It was their biggest victory over Rangers since the 1957 Scottish League Cup final. In that first season, O'Neill won a domestic treble with Celtic, the first time this had been achieved since 1968–69. Celtic then retained the league title in 2001–02, the first time since 1982 that Celtic had managed that feat. Celtic also qualified for the Champions League group stage, winning all of their home games but losing all of their away games.[citation needed]
