Red Bull have dismissed reports that Sebastian Vettel threw a tantrum during Friday's pre-season testing in Bahrain.

The German endured another difficult day behind the wheel of the RB10, which included his car coming to a halt before it had reached the pit lane exit, and BBC Sport claimed that Vettel expressed his displeasure with the team's performance.

However, the team responded to that rumour via its own Red Bull Spy Blog by ridiculing the report and poking fun at any suggestions of disagreement in their ranks.

They wrote: "A major news broadcaster posted the story this morning, along with the line 'No-one outside the team knows whether it happened or not, and those on the inside wouldn't say.'

"Eh? Run that by me again?

"I suppose it could be true. Maybe four world championships really have turned [Vettel] into a screaming primadonna."

Vettel failed to complete a lap at Bahrain, with the teams having no more testing before the Australian Grand Prix on March 16.
