By Phil Duncan Follow @@PhilDuncanF1 Lewis Hamilton could crack under the pressure of fighting to win his second Formula One championship, his former rival Felipe Massa has warned. Hamilton has been cast 29 points adrift of his Mercedes team-mate Nico Rosberg ahead of this weekend's British Grand Prix. The British star, who robbed Massa of the championship in the most dramatic of circumstances at the season finale in Brazil six years ago, has been hit with two mechanical retirements this year, while Rosberg has finished either first or second at every race. But Massa, speaking on the eve of his 200th Formula One start, believes Hamilton has been outsmarted by his team-mate so far this season.

The result might not be what you expect and this is part of sport, but @placeholder do not think like that.
