Chelsea have lost to Barcelona at this stage before and will have to pull off a mini miracle to survive.
“Everyone’s got unfinished business with Barcelona,” said Lampard. “They’re the greatest team in the world. They have been and still are. But that game [from three years ago] is still in our minds, but this is a different year and we have to try to beat them. They’ll be favourites but we’ve got belief. We know we’ll have to perform to our best to beat them, but we believe we can do it.”
