A tough followed with Ferrari, in which his car suffered more reliability problems, forcing him to retire from seven races. He was paired with Alain Prost, (who was also the reigning World Champion), and who took over as the team's lead driver. Mansell recalls one incident where at the 1990 British Grand Prix, the car he drove did not handle the same as in the previous race where he had taken pole position. On confronting the mechanics, it transpired that Prost saw Mansell as having a superior car and as a result, they were swapped without telling Mansell. After retiring from the race, he announced he was retiring from the sport altogether at the end of the season. This, combined with the fact that Frenchman Prost was not only a triple World Champion and the winner of more Grands Prix than anyone in history, but also spoke fluent Italian, whereas Mansell's Italian was only conversational at best, gave Prost greater influence within the Maranello-based team. According to Prost, Mansell only attended two or three mechanical briefings throughout the season, preferring playing golf. One notable highlight of the season was a daring pass on Gerhard Berger around the daunting high speed Peraltada corner that was later renamed in his honour. Approaching the corner for the penultimate time Mansell was bobbing from side to side in Berger's mirrors. Heading into one of the quickest corners on the calendar at the time, where the Ferraris had registered forces of 4.7g during practice, Mansell launched to the outside of Berger and flashed past to take second place.
