McLaren driver Lewis Hamilton believes he and reigning Formula One champion Sebastian Vettel could work as teammates.
Red Bull team principal Christian Horner had said earlier this week that Hamilton and Red Bull's Vettel couldn't work together because there "tends to be fireworks" between top drivers.
Hamilton had a difficult relationship with Fernando Alonso when they were teammates at McLaren for a single season.
However Hamilton told the BBC that world champions can race together "as long as there is quality in the team" citing his current partnership with another former F1 champion Jenson Button.
"A partnership can work as long as a team exists to win a constructors' championship and for the drivers' championship... I think it (working with Vettel) is possible."
Hamilton is under contract with McLaren for the next two years and is "committed to that, but it doesn't mean I can't promise anything... you never know what happens in the future."
