text: Nico Rosberg and Lewis Hamilton haven't always seen eye-to-eye in the past 12 months but the pair appeared to be singing from the same hymn sheet on Thursday. Fresh from being beaten by Ferrari driver Sebastian Vettel at the Malaysian Grand Prix on March 29, the Mercedes team-mates have been collaborating with their team to ensure the prancing horse doesn't gallop to victory at the next race in China. The duo attended Mercedes' Brackley base in the hope to find a winning formula come race weekend in Shanghai on April 10-12.

Speaking after the race in Malaysia, Mercedes motorsport boss Toto Wolff conceded that he was a worried man following the manner of Vettel's victory. Suggestions of another season of Mercedes domination in the wake of a comfortable one-two in the season-opening race in Australia were blown apart by Ferrari and Vettel. The four-time world champion beat Hamilton by 8.5 seconds, with team-mate Nico Rosberg a further four seconds adrift in third.

Wolff admitted that the German driver deserved to win and Ferrari got their tactics spot-on in the soaring heat . Despite searing heat of more than 30 degrees, Vettel's Ferrari was kinder on its tyres, stopping just twice compared to three for both Hamilton and Rosberg. And afterwards Wolff admitted: 'We were pretty sure the three-stop strategy would work for us. 'We probably went a bit too aggressive on set-up, which pushed us into a direction of a three-stop. 'But in the circumstances, with the high temperatures, they were able to go at a faster pace over long runs than us. 'We need to analyse why that was the case, and it clearly shows it's not going to be an easy one. 'It is clear they won the race, which is worrying. It wouldn't be right to say we lost it.' Hamilton (pictured) had to pit three times in the race compared to Vettel's two - in what proved a key factor .
