Should Hamilton go to Red Bull?
In any case, that's what Damon Hill thinks, suggesting to Lewis to look a bit outside of McLaren.

Lewis Hamilton began his Formula 1 career in 2007 driving a McLaren. The ties between the 2008 world champion and the British team are very close and it seemed unlikely until now that the driver would not remain loyal to his team.
But the recent arrival of Jenson Button, and especially his impressive results, have undermined Hamilton’s position within the team.
Damon Hill, world champion in 1996 with Williams, thinks it might be time for Lewis to seek a change: « He might look to leave McLaren. There’s something he might need to do, which is to leave the team he has been with since the age of 13. »
And Damon, who is not actually Hamilton’s manager, even has ideas for his future: « If I were in Bernie Ecclestone’s shoes, I would probably like to see Lewis teamed up with Sebastian Vettel at Red Bull. »
It now remains to know the real motivations of Lewis, whose contract with McLaren ends at the end of the year.
