For the Boca manager, his goalkeeper's quality is such that he merits an international call-up. "Rossi could easily be a goalkeeper for the Argentina national side," he said, speaking to 'Radio Continental'.
The Boco shotstopper has come under fire for various mistakes of late, notably during the 0-2 against Palmeiras which complicated things in the Copa Libertadores, but for Guillermo the criticism has been a bit harsh.
"I remember that they also criticised Pavon," he said, referring to Boca striker Cristian Pavon, who is part of Argentina's 23-man World Cup squad. "So I'm not too worried."
