Napoli boss Walter Mazzarri knows that his side will have to be perfection personified in their Champions League ties against Chelsea.
The Azzurri will take on the English giants in the next round of the competition as they attempt to reach the quarter-finals of the European Cup for the first time ever.
“Chelsea are one of the strongest sides in Europe,” the Stadio San Paolo tactician told Premium Calcio on Friday afternoon.
“After a period of crisis, they are rediscovering their continuity thanks to champions such as Didier Drogba.
“They beat Manchester City in their last game, a side who are dominating the Premier League, so that must mean something.
“The first game between us is at home, therefore the tie at Stamford Bridge will decide qualification. If we want to make it through then we’ll have to be perfect.”
Napoli progressed to the last 16 stage after taking four points off Manchester City in the group stage, thus demoting Roberto Mancini’s club to the Europa League.
