Milan chiefs know it could've been worse, despite Atletico's domestic form this season.
But Tassotti warned: "It is very difficult to think the draw went well, because every team in this round is very strong. We've got to improve over the next two months if we want to beat them. They are leading La Liga, while we are a bit further behind. There is time, though we've got to do a lot better to knock them out."
