(CNN) When Arsene Wenger became manager of Arsenal in 1996, his appointment was seemingly greeted with a mixture of bafflement and incredulity. -- a jibe at the Frenchman's apparent lack of credentials when it came to his less than stellar playing career or the fact that he had no experience of English football. Fast forward two decades later and Wenger has signed a new two-year deal, but the response from many Arsenal fans might be "Arsene Why?" But surely his greatest achievement to date has been his "Invincibles" of 2003/04, who went the entire league season without losing a single match. Aside from not winning the Champions League, the team haven't won the Premier League since 2004.
