Monday 20 April at 09:59 : Apr.20 (GMM) Bruno Senna has confirmed suggestions that his goal is to enter formula one perhaps as soon as this season

The 25-year-old Brazilian last week turned down Mercedes-Benz's offer of a 2009 seat in the German touring car series DTM

German news agency SID reports that the reason for the snub is that Norbert Haug could not guarantee the 2008 GP2 runner-up a formula one seat for 2010

It is claimed that Senna is now holding out for a drive this year, as names including Giancarlo Fisichella, Kazuki Nakajima, Sebastien Bourdais and Nelson Piquet come under increasing pressure to perform

"Formula one is the goal, which is subordinate to everything else this year," said Senna, whose uncle Ayrton died during the 1994 San Marino grand prix

SID reports that his biggest hope of a vacant cockpit this year is for the one currently occupied by his countryman Rubens Barrichello

"Bernie (Ecclestone) told me that I should not too tightly commit myself (outside of F1)," Senna admitted
