He never matched the Dutch driver's pace (Verstappen was quicker in qualifying for all the races), although the team largely stopped development on the car when Tom Walkinshaw bought it.
Rosset later stated that the cash-strapped team were unable to provide two identical cars, with a lack of spares, and they concentrated on the faster driver, Verstappen.
However, the team pulled out of Formula One after one failure to qualify at the 1997 Australian Grand Prix due to an uncompetitive and underdeveloped car, the Lola T97/30, and a breakdown in sponsorship from MasterCard.
"[2] Despite an eighth-place finish at the next race in Canada, which was ultimately the team's best result of the season, Rosset was in danger of losing his seat to Danish driver Tom Kristensen.
At a test at Magny-Cours, Rosset and Takagi posted almost equal times, with Kristensen around half a second slower, albeit with an older engine.
[7] Rosset's problems included missing out on qualification for the Spanish Grand Prix by 0.06s, and an injury during practice for the German Grand Prix which prevented him from taking part in qualifying, while in Belgium he crashed into the carnage of the 14-car pile-up on the first lap after being unsighted by the heavy spray, and was unable to take the restart.
A further failure to qualify at Tyrrell's final race in Japan, where he was hindered by a neck injury caused by a crash in practice, marked the end of his Formula One career.
Rosset later stated his belief that Tyrrell concentrated heavily on his Honda-backed teammate Takagi, and gave the Japanese driver an advantage in order to win favour from Honda.
[9] Encouraged by this performance, Rosset bought the Footwork FA17 chassis that he raced in 1996, and planned to enter it in a historic F1 series in 2009,[10] but ultimately did not.
