Perotti has failed to lift a trophy in his three years at Roma.
“I've always said that I won't end my career at Roma," he told ESPN.
“However, if I had to leave without winning something, it would be a bigger disappointment than Argentina's World Cup.
“We're strong, we know what we want and we have the chance to win. It would be great to lift a trophy at Roma.
“Ronaldo? The Italian League had recently lost a bit of appeal abroad. We know the level is high here.
“Juventus have reached two Champions League Finals, we've reached the semi-finals and the Italian level isn't as poor as some have said. With Cristiano it'll grow again."
