Even if Napoli had been down with ten men, that can't be an excuse for conceding 3 goals especially when they had the time and reorganize in halftime. Spartak plays smart, press accordingly, and manages to score more than enough to turn the game. Now things in this group look difficult for them but again Napoli can turn this around and qualify in the next phase. Btw who will think that Legia will be on the top with 2 wins in 2 matches...
I agree that it shouldn't be an excuse for Napoli even while they are in a situation like that. Because they are still a far better team than Spartak Moscow and it was a home match also. They conceded 3 goals and were able to only decrease the goal difference to one. Napoli must be unpleased with this result but they will move on and continue to perform great in the Serie A in my opinion.
