Martino was confirmed as the new Camp Nou boss just days after Tito Vilanova's shocking resignation over health problems as he continues his battle against cancer.
Martino, who steps down as Newell's Old Boys boss to take the two-year deal in Catalunya, is thrilled to get the opportunity to coach Lionel Messi and is crossing his fingers that he will be a huge success.
"For my career as a coach, with the players that Barcelona have, with Leo there, it's exactly what every coach wants," Martino told reporters at a press conference in Argentina. "I hope I can be as good as they are expecting and help them keep winning."
Martino reached a two-year agreement with Barcelona and was presented Tuesday afternoon at a press conference in in Rosario, Argentina. Despite having no coaching experience with a European club, Martino received the backing of Messi in recent days.
"I'm really happy that Barcelona considered me and my way of working. I have hopes that everything will go perfect, and, despite the [high] expectations, that everything will go great," the 50-year-old said.
"My first goal is to get adapted to the club with my people the best way. Then we have to fight for every competition we play."
Martino is the fourth Argentine to coach Barcelona, after Helenio Herrera (1958-60, 1980 and 1980-81), Roque Olsen (1965-67), and Cesar Luis Menotti (1983-84).
