Michael Schumacher is the final and leading target of the Goodwood Festival of Speed organisers as the seven-time F1 champ remains the only leading racing driver never to have graced Lord March's motoring pagaent.

The appearance of Alain Prost - the other major driver who had previously never appeared at the FoS - at the Festival on Saturday has put Schumacher at the top of the hit list. "We have been trying hard over many years to get both Prost and Schumacher to attend the Festival, now it's just Schumacher," says a spokesman for the organisers.

The German driver is understood to have been approached many times by Goodwood to make an appearance, but so far has resisted every offer. Since appearances at GW are often linked to sponsors, Mercedes-Benz may be able to persuade the all-conquering German to link a drive and appearance to a major presence from Stuttgart.

Prost's appearance was linked to his role as an ambassador for Tag Heuer watches, who celebrated the 80th anniversary of Mr Jack Heuer with a special reception at Goodwood.

The Frenchman is rumoured to have been concerned at his likely reception, given the portrayal of his tempestuous relationship with Ayrton Senna in the bio-pic of the Brazilian.

However, the hordes of cheering race fans who greeted the French ex-champion are understood to have pleasantly surprised Prost, and Schumacher can expect a similarly generous reception.
