Ramires knows they must focus on the task at hand.
"There is a lot of talk already about Barcelona but we as players don't look that far ahead," the 25-year-old told chelseafc.com. "We are concentrating on every single game as it comes. We respect Benfica a great deal, it is a massive club with a lot of tradition so there will be no talk of Barcelona. I am sure there will be plenty of talk afterwards if we progress but for now the focus is solely on this game.
"Everyone has high expectations of us but we go out there to play for the fans and we will try to remain in the competition as long as possible."
