Lewis Hamilton says he finds it 'funny' that other teams are complaining about Mercedes' current dominance of F1, saying it "has worked its arse off' and deserves the success it is experiencing.

The British driver joined the manufacturer from long-time employer McLaren at the start of the 2013 season, but after an indifferent 2013 season would go on to clinch the title ahead of team-mate Nico Rosberg in 2014 as the team grasped the new regulations most effectively.

Following his and Rosberg's similarly comprehensive performance in Australia, Red Bull's Christian Horner made a call for 'equalisation' to stop Mercedes being so dominant again in 2015 in the interests of the sport.

However, Hamilton has shrugged off the calls, saying Mercedes' team members have simply 'worked their arses off' instead of calling for ways to equalise the competition.

"I find it quite funny and interesting that the opinion is coming from individuals who have had so much success," he said. "Bearing in mind it has only been one race, so to already have comments like this is what I find funny.

"It was a big step for me to come to this team that had so many years of poor performance. They hadn't had the success of other teams and not once did this team complain to others in order to equalise things, they just worked their arses off.

"Joining that team and making that progress, now we are the best team, we have pulled together and done an amazing job. It is not just me here, there are 1000 people back at the two factories who are working day and night to build the best car and we have done that with the same rules and resources as the other teams have had. I am very proud of that."
