Fernando Alonso, and not Lewis Hamilton, is the man to take the fizz out of Red Bull's Sebastian Vettel and stop the German winning his fourth consecutive Formula One world championship.
Red Bull have an impressive record when it comes to meeting fresh challenges and the latest one is something completely different: how will Mark Webber's decision to quit the team upset the most impressive operation in Formula One?
Team orders or individual brilliance? Which should come out on top?
Red Bull have admitted that they are unable to control their warring drivers, Sebastian Vettel and Mark Webber, and have largely abandoned the concept of team orders.
Lewis Hamilton says the problems at Red Bull that came to the fore in Malaysia are down to them having a No1 and No2 driver.
OK, I admit that I don't get F1. I thought that it was all about the fastest guys winning races. But no, it's a team game stupid.
Red Bull had their 13th one-two finish here in Sepang with Sebastian Vettel edging ahead of a very competitive Mark Webber for his 27th Formula One victory, matching Jackie Stewart.
