Force India boss Vijay Mallya is optimistic for the second half of the season.

Vijay Mallya, team principal: The German Grand Prix marks the midpoint of the season and is a good chance to stand back and assess our performance over the first nine races. What is clear is that we have an excellent driver line-up and a car that is improving race by race, which gives us cause to be optimistic about the second half of the year.
