Yeongam, South Korea: Formula One's most experienced driver urged Lewis Hamilton to ignore his critics on Friday after the Briton shrugged off a dip in form to top practice for the Korean Grand Prix.
Brazilian Rubens Barrichello, 39, who is taking part in a record 319th grand prix, gave his support to Hamilton after the McLaren man dominated a rain-hit day to lead team-mate Jenson Button and German champion Sebastian Vettel.
"It is important the day that you understand you can only depend upon yourself. What others say doesn't matter. You need to be 100 percent right on your thoughts and you can put it out of your head," Barrichello said.
