Sunday 22nd September 1991
Another Nigel Mansell championship bid ended in heartache as well as semi-farcical circumstances at the Portuguese Grand Prix. Starting the race from fourth on the grid, Mansell drove superbly to take the lead. But during a pit stop, one of his tyres was not fitted properly, came off the car and began bouncing down the pit lane. With Mansell gesticulating frantically, his Williams mechanics ran to his car to attach another wheel. Mansell emerged 17th and broke a string of lap records to battle his way back up to sixth only to be black flagged and disqualified for illegally having mechanics work on his car in the pit lane. He drove into the pits, got out without a word to his team and headed tearfully back to his motorhome. “I just don’t believe it,” he said. “I’ve done everything I can and just don’t know what else I have to do.”
