This is Napoli's largest away win in European competition and equals their biggest margin of victory overall.
2022/2023 UEFA Champions League


Seven wins in a row, six goals scored - it was simply amazing from Napoli.
Ajax were really bad and their defending was unconvincing but you still have to be clinical and the visitors certainly were. They have humiliated Ajax in front of their own fans.
