Ferrari driver Sebastian Vettel says the Chinese Grand Prix is always full of surprises and will be difficult to predict.

In the season-opening Australian Grand Prix, the German beat Britain’s Lewis Hamilton to first place, but attention now turns to Shanghai this Sunday and a "demanding" track.

Speaking to 5 live, Vettel played down his winning start, saying: “It’s only one race, it’s only the start of the season." But that the Ferrari team has "evolved" since last year are in "a much better position".
