McLaren, replace Checo... Not going to happen, but Perez has hardly been a success, he seems to be able to go faster than Button, or finish the race, but not both. At current rates he's likely to finish the season with a third or even a quarter of Button's score, not good for constructors points. Massa at least is a reliable finisher and point scorer. Ditto Hulkenberg, his points haul would probably outweigh Telmex's contribution by quite some margin. Or Di Resta, or JEV... Alternatively, Porsche should snap him up for Le Mans, him in one car, Mark in the other, although that may be tempting fate.
