The strong impression Justin Wilson made with Minardi in the first half of his debut season was undone somewhat by some unconvincing performances following his switch to Jaguar.
Wilson could hardly have turned down the opportunity afforded to him after the British Grand Prix, but it was always going to be asking a bit much for him to impress in a still-growing team with just five races to go.
Wilson showed impressive potential at Minardi in matching his vastly more experienced team-mate Jos Verstappen for pace.
His ability regularly to make up places on the opening lap shows a racer's heart, especially because the pace of his Minardi meant he had to surrender them as the race developed.
First GP: Australia 2003
Best result: eighth
2003 position: 20th
Previous teams: Minardi
But he seemed to lose his spark on his move to Jaguar as he laboured to come to terms with his new team and car.
His first three races for the team were a terrible disappointment - the car lacked reliability and he was a long, long way from the pace of team-mate Mark Webber - a man he beat to the Formula 3000 title as recently as 2001.
At the US Grand Prix, the season's penultimate race, Wilson finally looked more convincing - qualifying respectably close to Webber and racing to the first point of his career.
That and a solid performance in Japan were not enough to keep him in a Jaguar drive for 2004 as the team opted instead for 20-year-old Austrian Christian Klein.
And as the options for a drive in 2004 diminish, the ramifications for Wilson's future as a Grand Prix driver could be severe.
