Fernando Alonso once gave envelopes containing more than £1000 to McLaren staff in a bid to gain favour with them over team-mate Lewis Hamilton, it has been claimed.
Though their relationship has healed since, the 2007 season saw all-out war between the two drivers. Alonso was the defending double world champion, while his British rival was the young debutant enjoying a debut Formula 1 season for the ages.
The two competitive racers clashed on plenty of occasions. Eventually, they were both pipped to the drivers' title by Kimi Raikkonen, and Alonso left to re-join Renault while Hamilton went on to become champion for the first time the following year.
