Senna dominated 1989 while Prost was stuck behind backmarker Rene Arnoux and others; the Brazilian also dominated 1990 and 1991. At the 1992 event Nigel Mansell, who had won all five races held to that point in the season, took pole and dominated the race in his Williams FW14B-Renault. However, with seven laps remaining, Mansell suffered a loose wheel nut and was forced into the pits, emerging behind Ayrton Senna's McLaren-Honda, who was on worn tyres. Mansell, on fresh tyres, set a lap record almost two seconds quicker than Senna's and closed from 5.2 to 1.9 seconds in only two laps. The pair duelled around Monaco for the final four laps but Mansell could find no way past, finishing just two-tenths of a second behind the Brazilian. It was Senna's fifth win at Monaco, equalling Graham Hill's record. Senna had a poor start to the 1993 event, crashing in practice and qualifying 3rd behind pole-sitter Prost and the rising German star Michael Schumacher. Both of them beat Senna to the first corner, but Prost had to serve a time penalty for jumping the start and Schumacher retired after suspension problems, so Senna took his sixth win to break Graham Hill's record for most wins at the Monaco Grand Prix. Runner-up Damon Hill commented, "If my father was around now, he would be the first to congratulate Ayrton."
