| "It's complete rubbish," the German, winner of nine grands 
				prix so far this season, said as he and Hamilton joined 
				factory-based employees on Tuesday to celebrate the team's third 
				successive constructors' championship.
 "He's on it as ever before, fully motivated and does massive 
				work hours also. I've seldom seen that from him in the last 
				years, such a large amount," he told Sky Sports television at 
				the team's Brackley headquarters.
 
 British media, whose criticism of Hamilton's use of Snapchat 
				during a news conference in Suzuka led to a backlash from the 
				driver who also walked out of another media session, had 
				questioned his state of mind.
 
 Monday's papers talked of a 'delicate ego', examined his 
				'fragile mental state' and suggested the Briton was losing it on 
				and off the track.
 
 "Executives were mouthing the word 'meltdown'," reported the 
				Times newspaper, which said the champion had gone from "cocky 
				prankster to sullen loser".
 
 Mercedes motorsport head Toto Wolff said it was clear the media 
				needed to produce headlines, building up and knocking down.
 
 "Lewis had a couple of tough weekends... if he recovers and has 
				a good weekend in Austin, he's the hero again," he said. "That's 
				why I'm pretty relaxed about it."
 
 The two drivers earlier visited the Mercedes high performance 
				engines facility at Brixworth, where they also joined staff for 
				a team photograph, signed autographs and posed for selfies.
 
 Mercedes won the constructors' title in Japan at the weekend, a 
				week after an engine failure denied Hamilton victory in 
				Malaysia.
 
 The three-times champion, who finished third in Suzuka on Sunday 
				while Rosberg won, is now 33 points behind the German and even 
				winning the last four races will not be enough if the other 
				Mercedes finishes second.
 
 No driver has ever won nine races in a season and not been 
				crowned champion at the end of it, but Rosberg expected a tough 
				battle right to the end.
 
 "It's going to be an exciting end to the season for sure," the 
				German told Reuters television. "A battle with Lewis as always, 
				it's always tough against him.
 
 "For me, it's just about looking at Austin. I'm excited to go 
				there, I know I have the chance to win and I want to make it 
				happen."
