Lewis Hamilton: Nico Rosberg will come back stronger in 2015

Two-time world champion Lewis Hamilton says he will have to come back stronger in 2015 if he is to stay ahead of Mercedes team-mate Nico Rosberg.

The Briton beat rival Rosberg to the title in Abu Dhabi on 23 November after a season-long battle with the German.

Hamilton, 29, also singled out Red Bull's Daniel Ricciardo and McLaren-bound Fernando Alonso as competition.

"Daniel Ricciardo has been doing an amazing job, it will be interesting to see what Fernando does in his car."

Mercedes claimed the constructors title for the first time in their history in Abu Dhabi thanks to Hamilton's win.

Speaking at the FIA's end of season awards dinner in Qatar on Friday, Hamilton added: "Nico's going to come back stronger and I'll have to make sure I come back even stronger to stay ahead of him."

Also being celebrated at the awards dinner in Doha was former Minardi and Super Aguri F1 driver Anthony Davidson.

The Briton, alongside team-mate Sebastien Buemi, won the 2014 FIA World Endurance Championship  with their Toyota Hybrid Racing team.

Anthony Davidson tweeted: "From @RyeHouseKarting to #Doha. Two British @fia World Champions! :-) #FIAPrizeGiving @LewisHamilton"

Runner-up Nico Rosberg posted this selfie on his twitter account, saying: "Cheers from Doha to everybody out there!"

Other award winners included Anthony Davidson, Sebastien Buemi, Petter Solberg, Jose Maria Lopez and Nasser Al-Attiyah
