Mercedes chairman Niki Lauda says everyone at the team are pulling in the same direction as they look to bounce back following Ferrari's win at Sepang.

After dominating the season-opening Australian Grand Prix, many expected it would be more of the same for Merc in Malaysia after Lewis Hamilton made it back-to-back pole positions for 2015.

However, Ferrari claimed a shock win as Sebastian Vettel used a two-stop strategy to come from second on the grid to end Merc's eight-race winning streak, which dated back to 2014 Italian GP.

Mercedes, though, have vowed to come back strongly and Lauda says they are all singing from the same song sheet.

"We all need to pull together to haul Ferrari and Vettel back in, there's no in-fighting in the team. That's totally clear for everyone," he told Germany's Bild am Sonntag.

During the 2014 season Hamilton and Rosberg often visted Brackley on separate days, but the latter posted a selfie of the two Merc drivers in a private jet on their way to the factory together.

Lauda says they all reviewed their disappointing outing at the Malaysian Grand Prix and are now looking forward to the next race at Shanghai.

"This time everyone attended, we have analysed the race as a big group and are now well equipped for China," he said.
