I think the issue is, if Button can't perform more consistently next year than he has this year, then Mclaren are going to need Perez to score big points. As next years car is an evolution of this one, its unlikely it will change radically. That's a lot of pressure on Perez. If he has to cope with the mind games on top of that I think he could be in for a tough time. I say again, I like Perez and think he has a lot of potential, but he's only 22. It was suggested in 2010 that Button was entering the lions den. Well I think that was a pussy cats cage compared to what Perez maybe experience.
