Leaping into the lead ahead of a hesitant Prost and spinning Williams ‘junior’ Damon Hill, Senna clung on until the Renault’s 100bhp advantage brought the inevitable and allowed his nemesis to win.
However, the Brazilian still came home second, and things would get even better at the next round – his home race in Interlagos.
Senna took advantage of hugely changeable conditions to take a sensational win while Prost crashed out, before claiming another famous victory by dominating a rain-soaked Donington to now lead the championship from the Williams man, 26 points to 14.
Still though, the Brazilian would moan and groan his way through these early races, and Ramirez says it was the only time he and the three-time champion came to verbal blows after the team was pushed to the limit.
Yet again dragging his feet over whether to race, this time before Imola and in relation as to whether Ford would permit McLaren to use an engine on parr with the works Benetton team, Senna turned up at almost the very last minute (15 minutes to be precise) before the first practice session after taking a red-eye flight from Sao Paolo to Rome – and then promptly put the car in the wall.
Ramirez, who had arranged the Brazilian’s flight-plus-private-jet-plus-helicopter to make it in time, had had enough.
“I’d never had a confrontation with Ayrton before that year,” he remembers. “We were all running behind because he arrived so late – I remember shouting at him: ‘It’s all your ****ing fault! We would have been OK, we didn’t have to be like this!'”
Senna would retire from the race with hydraulic issues, but Ramirez admits he found it difficult to remain angry with one of his closest friends in the paddock.
“At the end of it, when he realised he’d buggered up that particular weekend, he smiled when we were having a glass of something – I think that was his way of saying ‘Yes, I’m sorry, I’ve been a son of a bitch’.
