Chelsea boss Di Matteo won't change system in Terry absence
Di Matteo insists he will not change his approach, regardless of the opposition.
"It's important we keep our philosophy of how we want to win games," the Chelsea manager said.
"Going behind made it hard for us but we believe in our capabilities.
"It's not the first time we have come from behind to win. It was a very exciting game, a typical London derby with two good teams in good form.
"We lost control of the game and there was concern, but we came back."
