The former Fiorentina forward is in awe of his fellow Argentine, whom he believes has proven himself superior to the Uruguayan striker he replaced at the San Paolo
The latter left the San Paolo last summer to join Paris Saint-Germain, prompting the Partenopei to replace the Uruguay international with former Real Madrid star Higuain.
The 26-year-old has since netted 12 Serie A goals for Napoli and Batistuta is in awe of his compatriot's impact in Italy.
"It was not easy to take the reins from the Uruguayan, but Gonzalo is succeeding," the former Fiorentina, Roma and Inter forward told Il Mattino.
"Gonzalo churns out assists, returns to midfield, set outs attacks, pushes the team forward and is a presence in front of goal.
"He doesn't get the same number of goals, but I consider him to be a more complete player, so I prefer him.
"He came from Real Madrid, where he did well, and is a starter for Argentina, so he has nobody to envy in terms of experience."
Batistuta enjoyed a glittering Serie A career, scoring over 200 goals in Italy.
