by Boutsen and Prost as the Brazilian's tyres finally went off. Senna faded to finish fifth, but the battle for second continued between Boutsen and Piquet - Boutsen went out avoiding Piquet who was rejoining the track after having gone off - and then between Piquet and Prost, with Prost getting the better of the Williams driver who also lost third place to McLaren's Stefan Johansson who put in another strong drive. Both Ferraris blew their engines. Martin Brundle, who finished 11th in his Zakspeed, described his drive as "the time I got out the car thinking no human could have done [any] better".
