Just realized we can have a situation where we, Napoli, and Dortmund finish the group with 12 points each:
Arsenal vs Marseille (Arsenal wins)
Dortmund vs Napoli (Dortmund wins)
Napoli vs Arsenal (Napoli wins)
Marseille vs Dortmund (Dortmund wins)
Arsenal - 12 pts.
Dortmund - 12 pts.
Napoli - 12 pts.
Marseille - 0 pts.
We need to score as many goals as possible against Marseille to avoid losing out on goal difference.
