Lewis Hamilton was 'really surprised' by one thing Fernando Alonso did before his F1 debut.
Hamilton's debut Formula 1 campaign was marked by a tense intra-team battle with Alonso, who had joined McLaren for the 2007 F1 season after winning back-to-back drivers' championships with Renault.
Ron Dennis had signed Alonso, considered the most talented driver on the grid after Michael Schumacher's retirement, and also decided to introduce McLaren's young talent, Lewis Hamilton, to F1 that year.
Hamilton and Alonso fiercely competed throughout the season, ultimately costing each other the title, which was won by Kimi Raikkonen, securing Ferrari's most recent drivers' championship.
