Napoli coach Rafael Benitez has said that he is still thinking "positive" despite his side needing to beat Arsenal by three clear goals to progress in the Champions League.
"We need to think positive; this is a team that is still growing and for long periods tonight we had the kind of performance I want to see in Serie A," Benitez told reporters after the game.
"Let's not forget Borussia have played with the same coach (Jurgen Klopp) for six years and were in the Champions League Final last season.
"I saw character today and the team wanted to score and win today, regardless of the venue. Obviously Borussia are very fast and talented, so they are tough to take on."
The final Group F game will be played on December 11.
