Chilton is not likely to set the game on fire, but equally he's a long way from the worst of the pay drivers we have had in the past. He's decent but unlikely to be anything special, although we have seen drivers perform better in F1 than in lower series before. We'll probably noy notice even if that is the case though, unless Marussia deliver a really decent car or he blows Glock away - both of which i'd rate as highly unlikely
