Ayrton Senna: A man of charisma (7.)

Senna originally planned to move to Williams for the 1993 season. Williams driver Mansell retired from Formula One after his world championship title in 1992.
But Senna was surprised by a former rival: Alain Prost, who re-entered Formula One with Williams after a year out, had made arrangements. Prost’s contract stipulated that Ayrton Senna could not become his team-mate. This meant that Senna’s Williams option for 1993 was off. He had no choice but to stay at McLaren if he did not want to miss a year.
