Lewis Hamilton may already be "even greater" than F1 legends Ayrton Senna and Michael Schumacher.
"Hamilton has a talent that is possibly even greater than that of Ayrton and Schumacher," he told ESPN Brasil.
"The only thing he lacked was maturity. He has progressed on that, and today you see the final product."
Expanding on how Hamilton has improved in recent years as he matured, Barrichello said of the 35-year-old: "When I listened to the radio in Brazil, I noticed that he is incredibly calm, passing on information, saying what he does and doesn't need.
"The perfect driver would have Ayrton's skill, Schumacher's courage and Hamilton's coordination. It would be something to see!" he said.body check tags ::
