Sunday 30th September 1990
The first of three retirements in the last three races of the season by Ayrton Senna allowed rival Alain Prost to win the Spanish Grand Prix, team-mate Nigel Mansell making it a one-two weekend for Ferrari. Senna’s day ended when the radiator on his McLaren was punctured by debris from backmarker Yannick Dalmas, allowing Prost to coast home and cut his lead to nine points. The weekend was overshadowed by a serious crash involving Martin Donnolly on the Friday which ended his career.
