By the summer of 1998, Alex Ferguson had firmly established himself as one of English football's most successful managers. His trophy haul included four Premier League titles, a single League Cup, and three FA Cup victories.

Perhaps for the first time in his United career, Ferguson had met a managerial match in Wenger. In this series, we follow the tactical evolution of arguably Ferguson's most successful Manchester United side, all while following their progress through each domestic and European competition.
