While Jaime Alguersuari continues to be listed among the potential candidates for the three remaining vacancies on this year's F1 grid, he could be poised to lose the one alternative option on the table.
The Spaniard was forced to sit out the 2012 campaign after being axed by Toro Rosso shortly before Christmas, but insisted that he had a budget in place to make a play for any seat that may become available for 2013. While several doors have already closed on him, notably at Lotus and Sauber, Alguersuari remains in the frame at Force India, Caterham and, as of Monday, Marussia, following Timo Glock's unexpected split with the Banbury operation.
Ironically, however, the German's exit could actually deny Alguersuari any chance of racing this season.
While maintaining that he wanted to address what he regarded as unfinished business in F1, the Spaniard revealed that he had been offered the chance of joining BMW's DTM line-up. His desire to remain in single-seaters, however, left the German marque on the hook and it now appears that Glock could be its preferred option. The former Jordan and Toyota driver has already been confirmed as taking part in this week's group test with the latest BMW M3 DTM and could be shoe-horned into the line-up should things go well at the Circuit Ricardo Tormo in Valencia.
Alguersuari, therefore, may come to regret his blinkered pursuit of an F1 return, with others – notably Vitaly Petrov, Luiz Razia and Bruno Senna – understood to have better financial backing with which to pursue the open seats, and Jules Bianchi and Adrian Sutil already thought to be Force India's preferred options.
