Three-time F1 world champion Niki Lauda has hailed Lewis Hamilton's achievement of winning his third title in today's US Grand Prix in Austin, and says he will "get better and win more".
Lauda, who is part of Hamilton's Mercedes team's management, said today's race was a fitting way to celebrate Hamilton's elevation to the three-time champions' elite.
Victory meant he outscored teammate Nico Rosberg and Ferrari's Sebastian Vettel by enough to points to ensure him of the championship.
"Very good, can't complain, the best race ever today to watch," said Lauda.
"Now he's only as good as I am – I'm joking. He will get better and win more, I tell you.
"I was worried that Vettel could pass Nico and delay the whole thing."
Wolff delighted to add drivers' title
Mercedes team principal Toto Wolff added his congratulations to Hamilton's feat, and says he deserves all the accolades.
"Lewis deserves the world championship, he was brilliant in his driving," said Wolff. "Nico was a little less lucky. We need to build him up again in the next few days.
"But it's an amazing feeling, double constructors' and drivers' champions."
Talking about today's race, Wolf admitted: "I'm not sure we got it completely right, the last safety car saved Lewis's race, but he deserved the luck.
"There were a lot of marginal calls, without the [Daniil] Kvyat incident at the end he wouldn't have made it, but now it's done."
