It has often been said that Heinz-Harald Frentzen is the only man in F1 who Michael Schumacher fears but the Jordan man has rarely had the equipment to give his compatriot nightmares.
The pair's rivalry dates back to 1989 when HH-F beat Schumacher in the German F3 championship. Then when they both drove for the
Mercedes sportscar team the following year, Frentzen consistently clocked faster times than his team-mate.
After four years of going nowhere in F3000, Frentzen was finally given his chance in F1 by Sauber in 1994. He scored a respectable seven points on his way to 13th in the championship.
He caught the eye the following year, scoring 15 points and finishing on the podium in Italy.
Frentzen stayed at Sauber for '96 amid speculation that Williams had lined him up to replace Damon Hill. The rumours proved to be true and he duly signed on to partner Jacques Villeneuve for 1997.
However, things did not go to plan. While Villeneuve went on to win the championship, Frentzen struggled to make an impression and managed only one win at Imola.
He stayed put for 1998 but, shorn of its works Renault engine, the
Williams was not the same car. Frentzen only managed 17 points and was given the push at the end of the season.
It was only when he signed for Jordan in 1999 that Frentzen started to show what he was really capable of. The German was the revelation of the season, scoring two wins on his way to third in the championship.
