Sebastian Vettel continued to tease as the debate again raged over whether he will aid Red Bull team-mate Mark Webber in Sunday's title-decider in Abu Dhabi.

For the final pre-race press conference of the season yesterday involving the drivers, the FIA threw together the four championship protagonists - Fernando Alonso, Mark Webber, Sebastian Vettel and Lewis Hamilton, the latter trio eight, 15 and 25 points adrift of the Spaniard respectively.

Vettel said: "As to what happens on Sunday, if the situation occurs then I think we know we're driving for the team.

"We (he and Webber) have had some occasions this year where we have got close and it didn't look too good. So I think the main target is not to repeat that, and the rest we will see."

It underlines the fact with one race remaining, in which for the first time in Formula One history there are four drivers still in the hunt for the title, they each have a story to tell.

The one surrounding Vettel and Webber remains the most intriguing, and after offering a subtle suggestion in Brazil on Sunday he may work for Webber, the young German dropped a further hint.

Team principal Christian Horner has already stated there will be no team orders, so any decision rests solely with Vettel, technical chief Adrian Newey has urged the 23-year-old to be "magnanimous," whilst owner Dietrich Mateschitz has simply told his drivers to race and "whatever will be will be."

It all comes down to Vettel who may have it within his power to ease to one side and make Webber champion, so denying Alonso.

"There are lots of things, more important things happening before we enter this possible stage, whatever the scenario," said Vettel.

"First of all we have to focus on getting the car ready (for Friday), prepare it, have a solid qualifying.

"Last year was a very tricky session here I remember, so there are lots of things to do, things that we should spend our energy on, more important things."
