As a result of the spontaneous withdrawal of its main sponsor, the Fondmetal team ended its Formula 1 involvement after the Italian Grand Prix . Since there were only 26 pilots left, for the first time since the Japanese Grand Prix in 1987, all participants who had traveled could qualify for the race, as there were just as many starting places available.
As a result of an engine problem at the start of the warm-up lap, Michael Schumacher had to start the race from the back of the field. Mansell achieved a start-to-finish victory. The ninth win by a driver in one season was a new record at the time.
Until his pit stop on lap 23, Patrese was in second place. The stop was delayed due to a problem and Patrese came back on track in fourth behind Senna and Berger. He caught up with Berger within 15 laps and found her next to him when he wanted to turn into the pit lane. Patrese's front wheel hit Berger's rear wheel, causing Patreses Williams to take off and tossing him several meters through the air. The Italian survived the accident with minor injuries. Several pursuers damaged their vehicles when they ran over debris that was lying on the route. Among other things, Schumacher had to make two unscheduled pit stops as a result. The Williams team saw Berger as the cause of the accident and protested that he was allowed to continue the race without being disqualified. However, the stewards judged the incident as a normal racing accident and therefore did not issue any penalties.
More than 37 seconds behind Nigel Mansell, Gerhard Berger crossed the finish line in second place. After a total of four pit stops, Ayrton Senna was third ahead of Martin Brundle, Mika Häkkinen and Michele Alboreto .
