Gerardo Martino must make a winning start to life in charge of Barcelona or risk coming under pressure from the Camp Nou faithful - according to former Blaugrana striker Raul Amarilla.
The Argentine was named as Tito Vilanova's successor last Friday following successful stints with Paraguay and Newell's Old Boys, but Amarilla believes there will be far more pressure on him to succeed with the Catalans.
“Hopefully wins arrive along with Tata Martino in Barcelona, because if not it will become very hard for him," he told Esports en Xarxa.
“The people and the fans do not know him which means there is added pressure.”
The former striker, who spent three years with the Blaugrana between 1985 and 1988, then revealed that he was not surprised by Barcelona's move for Martino, despite the fact he has never coached outside of South America.
“I was not surprised that Barcelona signed Tata because he is one of the best coaches at the moment,” the 53-year-old told Esports en Xarxa.
“Barcelona have always sought the best and in South America he is one of the technicians with the most popularity.”
Martino succeeded Amarilla as Paraguay boss in 2007.
