Emmanuel Adebayor - 3 hat-tricks
Given the feeling of hatred towards Emmanuel Adebayor at the Emirates Stadium, it's hard to believe that the Togolese striker used to play for Arsenal - let alone score hat-tricks for the club.
But that's exactly what he did during his time with the Gunners, notching his first treble in an emphatic 5-0 win over Derby in September 2007.
The Rams were once again on the receiving end in the reverse fixture later that season, with Adebayor at his brilliant best in a 6-2 win at Pride Park.
He was at it again next season, scoring three for Arsene Wenger's side in a 4-0 win over Blackburn.
