Lewis Hamilton versus Jenson Button has a long way to go before it can match some of the all-time classic F1 teammate wars. Here's a list:
Alain Prost vs Ayrton Senna (McLaren 1988-89): The daddy of all rivalries. Senna won the 1988 title in controversial circumstances, and the pair's relationship grew increasingly bitter the following year as jealousy and enmity consumed them. It ended in a notorious collision at Suzuka, which saw Senna disqualified post-race and Prost awarded the title.
Nigel Mansell vs Nelson Piquet (Williams 1986-87): Another rivalry so punchy it would make today's drivers wince. Piquet, the established champion, did not take kindly to brash upstart Mansell, and was infuriated not to be awarded No. 1 status at Williams. They took so many points off each other during the 1986 season that they let Prost through to become champion.
James Hunt vs Jochen Mass (McLaren 1976-77): How would Hunt have coped in the age of Twitter? He would not have been short of followers, that is for sure. The British maverick famously decked a marshal at the 1977 Canadian GP after colliding with his teammate (whom he called 'Herman the German') as he was in the process of lapping him.
Gilles Villeneuve vs Didier Pironi (Ferrari 1981-82): A rivalry tinged with tragedy. After Pironi refused to obey team orders at Imola in 1982, Villeneuve swore he would never speak to his teammate again. The Canadian died two weeks later at Zolder, trying to beat Pironi's qualifying time.
Fernando Alonso vs Lewis Hamilton (McLaren 2007): Alonso arrived as the double world champion, Hamilton was the rookie who finished on the podium in his first nine races. The Briton refused to give way to Alonso in qualifying in Hungary and the Spaniard blocked his attempt to set one last time.
