3. James Hunt v 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 team-mate (whom he
called ‘Herman the German’) as he was in the process of lapping him.

4. Gilles Villeneuve v 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 team-mate again.
The Canadian died two weeks later at Zolder, trying to beat Pironi’s
qualifying time.

5. Fernando Alonso v 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.
