Back in 1993 I can remember Benetton progressing their technical development at an impressive rate and a bunch of media talking to Tom Walkinshaw about drivers.
Williams were dominant and Alain Prost was on the way to his fourth and last world title. But, before the end of the year, in Portugal, it became known that Ayrton Senna was going to be a Williams driver in '94.
Prost announced his retirement but a lot of people thought it was only because he couldn't face driving alongside Ayrton again. Reigning champion Nigel Mansell, meanwhile, had gone off to the US in a huff when Frank Williams refused to pay him what he thought he was worth.
He was busy winning the IndyCar crown at the first attempt - a hugely impressive accomplishment considering he'd never driven on an oval in his life.
