Nico Rosberg romped to victory at the Japanese Grand Prix on Sunday, piling more pressure on Lewis Hamilton as he closes in on a first Formula One world title.
Rosberg claimed his first Suzuka win from pole as Hamilton took third after a horror start, the German stretching his lead over his Mercedes rival to 33 points with just four races left this season.
"Woooooooh!" cried Rosberg over team radio after his ninth victory of 2016 and his fourth in the last five races.
"Thanks a lot, guys. An Amazing weekend and congrats on winning the constructors (championship)," he added after he and Hamilton wrapped up a third successive team title for Mercedes.
"It's 33 points, but I'm not focused on that. There's still a long way to go so I'm just keeping my head down."

"I just got a wheelspin. I made a mistake, then I was just working my way up from there — it was tricky but I did the best I could."
Hamilton vowed to fight on with a maximum of 100 points still available but admitted: "It's a healthy margin for Nico. I'll give it everything I've got.
