5) Arsenal have history on their side
Although their recent record against the big sides is poor, Arsenal actually have the best success record at Stamford Bridge of all the teams in the Premier League, having won there seven times in total. Before Jose Mourinho came along, Arsenal beat Chelsea regularly, and it was only a couple of years ago that they recorded a famous 5-3 win at the home of their London rivals. The Gunners’ poor run in big away games can’t go on, and if they are to win anywhere, history suggests it might be at Chelsea that they find success.
