But I still think we are in a superior position since we were able to keep a clean sheet at home. This means that for every goal we score they have to score two to go through
The statement is not quite correct. They don't have have to score 2 goals for every goal Liverpool score, all they need is to win the match regardless of the scoreline and number of goals scored by Liverpool, or avoid a scoring draw to force extra time and penalty(If there's still no winner after extra time).
