“I want to thank president [Maurizio] Zamparini for believing in me,” he told La Gazzetta Dello Sport.
“I am learning the Italian game. I was scared at first in terms of it being different as I was used to Argentina, but now I am used to the tough defenders.
“I am happy with Rossi, but I must admit there was some tension at first when I wasn’t able to express my football.”
