Hamilton 'speechless' amid Mercedes F1 celebrations

Lewis Hamilton has described his two years with Mercedes so far as "the best of my life" as the team celebrates its first constructors' championship.

The Russian Grand Prix saw Hamilton lead home team-mate Nico Rosberg for a one-two which confirmed Mercedes' constructors' title with three rounds still to go. Since then, both drivers and senior team members have been visiting the team's factory in Brackley as well as the home of Mercedes-Benz High Performance Powertrains (HPP) in Brixworth to join in the celebrations.

Having joined Mercedes from McLaren at the end of 2012, Hamilton said it was a move that had been right for him on both a personal and professional level.

"I'm actually speechless at this moment," Hamilton said. "What an incredible feeling it is to be stood in front of all these incredible people. You almost have to take a step back and just think about what we've achieved together. I know it's been a long road and many of the team have had to work through tough times to lay the foundations for what we're seeing today and I'm incredibly grateful for all of their hard work.

"These past two years have been the best of my life - and that's all down to everybody standing here today. The effort and the synergy here is unlike anything I've ever seen and I'm excited for the future."
