The Argentine believes Italy's top flight is "a big step up" from Spain in terms of tactics and and feels he has benefited from the competitive nature of the leagueNapoli striker Gonzalo Higuain feels he has become a better player following his debut season in Serie A.
The Argentina international scored 24 times in all competitions last term following a move from Real Madrid in July - helping Napoli to the Coppa Italia title and a third-placed finish in the Italian top flight.
Having previously been at Santiago Bernabeu for six years, Higuain claims the increased competition in Italy has helped improve him as a player.
"When I went to Spain it was a risk because I was really young," the 27-year-old told El Pais.
"But I quickly learned the game and I grew as a result. Serie A has been the same for me - except it's a more competitive league.
"Maybe the quality of the games is slightly less (than Spain) but from a tactical point of view it's a big step up.
"The defenders in Italy are stronger and that makes me better. Serie A is played in a different way to other leagues.
"I've become accustomed to playing against four defenders throughout my career but in Italy I have to play against five."
Higuain is set to feature at his second World Cup in Brazil, having scored four times in as many games during the 2010 tournament in South Africa.
