#2 Litmus test for Napoli's dogged defence
Napoli have the meanest defence in the league behind obviously Juventus, conceding only 18 in 25 games. But they have posted the best figures since the turn of the year, letting in on only three occasions in seven outings, and none in the last four.
The Partenopei went through the whole month of February without conceding in the league. The only occasion they were beaten at the back was at Zurich in the Europa League. So that's five clean sheets in the last six.
However, Juventus would be a true test of their defensive mettle. The Bianconeris are a different kettle of fish and pose a challenge unlike any other. Even though the champions are plagued by their own fair share of issues, still have the attacking might to take any defence apart.
Napoli especially are aware of this, having conceded 10 in six games to their Turin counterparts.
