Lewis Hamilton has dismissed Red Bull boss Christian Horner's suggestions that he and Sebastian Vettel could not race well in the same team.
Horner had said that there could be "fireworks" were that to happen, after speculation linked McLaren driver Hamilton with a move to Red Bull.
But Hamilton said: "Fernando [Alonso] and I were very competitive.
"Look at me and Jenson [Button]. World champions can race together as long as there is quality in the team."
Speaking at this weekend's Malaysian Grand Prix about the prospect of racing in the same team as reigning world champion Vettel, Hamilton added: "A partnership can work as long as a team exists to win a constructors' championship and for the drivers' championship.
"With our team being a manufacturer, it means equally as much to them to win the constructors' as it does the drivers'.
"I don't know if that's the same for them [Red Bull]. It doesn't necessarily affect them because they're not a car company, but I think it [working with Vettel] is possible."
Red Bull adviser Helmut Marko appeared to open the door to a possible move when he was recently quoted as saying "with his aggression and speed, Hamilton must always be a topic".
However, team principal Horner then played down the possibility of the two champions becoming team-mates, saying: "It's difficult to see how you could have two drivers of Lewis's and Sebastian's calibre under one roof.
"There tends to be fireworks as we saw with Fernando Alonso and Lewis [when they were McLaren team-mates in 2007]."
Hamilton's McLaren car performed well in Friday's practice in Malaysia where he finished second in first practice and third in the second session, and insisted the ongoing speculation was not affecting him.
"It's not frustrating. Whatever you are faced with you have to try and turn into positives," he said.
"The positive thing is I'm being talked about, and that's a great thing, which means I'm not forgotten. Another positive is that potentially other teams are interested in me, as well as my own team, which hopefully makes my team hungrier for me.
"But it doesn't distract us, and I've made that clear to my team boss [Martin Whitmarsh]."
As far as the future is concerned, the former world champion appeared to be open-minded.
Hamilton added: "I'm contracted for the next two years and I'm committed to that, but it doesn't mean I can't promise anything.
"I am focused on my job now and I want to win world championships here, and I hope that continues, but you never know what happens in the future."
