12 Chelsea managers Arsene Wenger has faced in the last 21 years – #4 and #7 are his greatest enemies

9. Andre Villas-Boas (2011-2012)

Such is the nature of modern football and the short length of time afforded to Premier League managers, Andre Villas-Boas and Wenger only met once. That said, it was an eight-goal thriller with the Gunners running out 5-3 winners. It was 3-3 with just 10 to play, before Van Persie scored twice to complete his hat-trick and send the away fans home happy. Andre Santos and Walcott scored the other two goals.
