Chelsea midfielder Juan Mata says their Champions League tie with Benfica is not over.

The Blues now take a 1-0 lead back to Stamford Bridge.

"This game was very important to us, the goals scored away from home takes on great importance, but now we must reaffirm our superiority at our own stadium and in front of our friends.

"We face a very strong team, but we have been patient and we have exploited one of the few chances we had to be able to take home the victory," said Mata.
