Chelsea midfielder Nemanja Matic says past form will count for nothing at Arsenal tonight.
The Gunners lost both of last season's League encounters - after having men sent off - but Matic is wary of Arsenal's threat and believes recent meetings will count for little in the heat of battle.
"It doesn't mean anything because every game is a different story," he told Chelsea's official website.
"They are a good team and they will try to find chances, especially at home in their stadium.
"It's going to be a very hard game, we respect them a lot, but we also know our qualities and we will try to use them."
