#1 2007 Hungarian GP
Come 2007, there was a new kid on the block in F1 and he had a chip on his shoulder. If McLaren thought they were going to let Lewis Hamilton be their number two driver, they had another thing coming. In a short time, Hamilton was turning heads in the sport and it wasn't sitting kindly with his teammate and former World Champion Fernando Alonso.
The much-publicised feud between the pair came to a head at the Hungarian GP when Alonso allegedly held up Hamilton during qualifying which forced the Brit behind his Spanish teammate at the front of the grid.
Alonso was subsequently given a five-place penalty and had to start in sixth while Hamilton started on pole. The incident meant that McLaren didn't score any constructors points in the race and would come to be the start of a rocky relationship between both drivers for years to come.
Hamilton would go on to win the race ahead of Kimi Raikkonen's Ferrari by the narrowest of margins while Fernando Alonso finished outside the podium spots in fourth.
