BMW and Alex Wurz

Alex Wurz has emerged as a possible candidate to drive for BMW's new works team in 2006.

The 31-year-old Austrian, who since 2001 has led McLaren's testing charge, admitted to the 'APA' agency that a return to the grand prix grid 'is possible.

''You know you are still alive in formula one,'' Wurz smiled, ''when you see your name again in the newspaper! It is possible that I will race next season but it is difficult.''

According to the Austrian press agency, BMW's executive committee in Munich are keen to put at least one German-speaker at the wheel next year. Although Nick Heidfeld is the top choice, his future is very much in the hands of Frank Williams, who can activate an option on his contract.

And whether 28-year-old Heidfeld needs to stay at Grove, it is clear, depends on the outcome of 'Buttongate II'. ''Frank Williams holds the key,'' Alex agreed.
