The Blues defeated Qarabag 6-0 in their opening group game, but they would be underdogs against Diego Simeone’s side.
“I expect to see a brave Chelsea tomorrow,’ said the defender. “We know we are facing a highly experienced team in the competition. After being one year away from Europe we want to do it right.
“We know it’s complicated but we are going to try and get the three points, play our game and we know we have to play a perfect match in order to get them.”
