Lavezzi is in Argentina preparing for the Copa America and looked back over the campaign.
"I have done well at Napoli and am satisfied with my season, but I know I ought to be more incisive in front of the net.
"I realise I ought to score more goals, as it would've been a lot better," he told Tyc Sports.
El Pocho only managed six goals in 31 Serie A games this season.
"I want to be a regular protagonist with the Seleccion shirt and am really fired up. We're playing on home turf and have a great chance of winning the Copa America.
"I realise it all depends on me now to deliver and prove I deserve my place in the side. I'm ready."
