"This new adventure is very important for me and I don't want to get it wrong," said the 26-year-old in a Press conference.
"I am feeling much better now after my knee injury and hope to be training with the team as soon as possible. This is an important step for my career, as Serie A is very tough.
"I've always liked Catania, as they play excellent football here, and admittedly the fact there were already so many Argentines in the side pushed me towards them.
"I hope to bring my experience to this team and even take them into Europe. I can play on the right or the left of attack, so I am at the complete disposal of the Coach. I can also play centre-forward, although it is not my ideal position."
