With United in UEFA Champions League action this week, we decided to ask a question based on the competition in its present format.
Although it was a bad night for Sir Alex's side, Marseille qualified in dramatic fashion with a 7-1 thumping of Dinamo Zagreb.
The Reds have been involved in FIVE European games that have produced seven goals or more since the inception of the Champions League in 1992/1993.
Out of the interest, the highest aggregate for a single game is Monaco's 8-3 win over Deportivo La Coruna in 2003.
