Arsène Wenger has shocked the soccer world with an unexpected announcement that he will stand down as the manager of Arsenal Football Club at the end of the season. The Frenchman arrived in London as a relatively unknown figure in 1996 and went on to oversee the most successful period in the club’s history. He was the first foreign manager to win the Premier League, a feat he accomplished in his first full season, and five years later his team became the first to go all season without losing a single Premier League game. His playing style, training, and dietary techniques revolutionized the sport in England. His team was no longer able to compete for the championship in his later years, but Wenger won a record seventh FA Cup last year.
