Napoli coach Rafael Benitez has admitted that he could rotate his squad ahead of their opening Champions League match with Borussia Dortmund on Wednesday.

The Naples outfit, who are also in the same group as Arsenal and Marseille, picked up a 2-0 victory over Atalanta on Sunday to maintain their 100% start to the new Serie A season.

In-form duo Marek Hamsik and Jose Callejon began the match on the bench at the weekend, and Benitez has hinted that he may make further alterations to his side ahead of facing the German side.

"Of course the match against Borussia Dortmund is going to be very difficult, but I know that a win is very important to increase the self-confidence of each player," Benitez told reporters.

"We still have many matches to play and the possibility to use 18 players out of 23-24, which is going to be very useful in this championship."

Napoli are currently top of Serie A.
