Webber not ruling out quitting Red Bull

Mark Webber on Friday would not categorically deny rumours he is set to quit Red Bull and possibly F1 after next Sunday's Abu Dhabi Grand Prix.

After making critical comments at Interlagos about the team's approach on Thursday, the big rumour in the paddock now is that the Australian is set to leave.

The chance he will simply retire – particularly if he wins the world championship – is considered high, although some believe he might be signed by Ferrari to replace the struggling Felipe Massa.

When asked if he is leaving Red Bull for 2011 despite having signed a contract, the 34-year-old told BBC Sport: "That's a pretty big step to take.

"As long as I'm enjoying my driving and performing really well, then of course I'll be here next year," added Webber.

But in a separate interview, Webber said only that there is "a good chance" he will still be at Red Bull next season.
