No need to revisit 2014 rivalry with Rosberg - Hamilton

Lewis Hamilton says there is no need to sit down with his team-mate Nico Rosberg and go back over the events of last year ahead of their upcoming title campaign.

Hamilton beat Rosberg to last year's championship after a tense battle that boiled over at the Belgian Grand Prix when the two collided on track. The team took disciplinary measures against its drivers and set out new rules after the collision, and Hamilton says it is not necessary to reinforce that message this year.

"I don't really know what to say about that," he said. "We had a lot of races last year where we did really well and we plan to do the same thing in terms of trying to win for the team. We haven't sat down and discussed anything about last year. I think we learned a lot through the year last year, so there is no need to discuss it."

Following pre-season testing, it looks as though the Mercedes duo are set to fight for the title between themselves, but Hamilton says it is more fun when a driver from a rival team is involved as well.

"I think it's more exciting when you're battling another team. When I was growing up watching F1, it was more fun when I was seeing two teams fighting each other. Having a competition within a team is still exciting, but it's just different when you are having competition with other teams."

Hamilton has not changed his approach to F1 this year, but said it is impossible to replicate his preparations exactly.

"Every winter is different, so it's hard to replicate the same winter each time. The feeling is different when you arrive at the first test, the feeling fitness wise is always different - last winter in testing I don't remember being sick, but I was sick this time for example. All the steps I've generally taken have been to approach the season the same."
