Napoli midfielder Gokhan Inler insists they'll get over their mini form slump.

The Azzurri again failed to get the full points ahead of a Champions League match, only managing a 0-0 draw with Lazio on Saturday evening.

"We certainly deserved to bring home all three points and it's a shame that Edinson Cavani's goal was disallowed, as I don't think Christian Maggio was offside," said Swiss midfielder Inler.

"If we made a mistake, then perhaps it was that we weren't incisive enough in the first half.

"I am confident that if we play this way in the next few rounds, then we can close the gap from the top of the table."
