Mindful of how much Alonso had outperformed him in , Trulli improved markedly the next year. For the first half of the season he was the better of the two Renault drivers, racking up regular points and podiums. At Monaco he finally took his only victory after a brilliant display from pole position. Having performed so well, the Italian was eager to stick with the team for 2005, but his relationship with team-boss Briatore soured. A last corner error which allowed Ferrari's Rubens Barrichello onto the podium in France enraged the team, and from that point his days with the French manufacturer were numbered. He did not score any points after the French Grand Prix and was consistently off the pace during races. He later accused the team of favouring Alonso, but the reasons why his 2004 season deteriorated have never been properly identified. He was sacked three races before the end of the season and replaced by World Champion Jacques Villeneuve, despite leading his teammate in the championship at that point. Trulli had already agreed to drive for Toyota in 2005, and his early exit from Renault allowed him to take up his new seat for the last two races of the 2004 season, replacing Ricardo Zonta.
