Michael Schumacher looks set to test a GP2 car soon, as the record-breaking multiple F1 world champion steps up his bid to return to the sport with Mercedes GP and compete in F1 2010.

According to reports by British newspaper, The Mirror a 'top secret' outing is being planned in the Middle East, something that will fuel hopes the 40-year-old will come out of retirement.

While the specific site for the test has not been disclosed, it is thought it could be held in Abu Dhabi - scene of the 2009 F1 finale, or in Bahrain, which will of course kick off the 2010 FIA F1 World Championship.

It is believed it will last for at least a week, as Schumacher and Mercedes-Benz are keen to see if the neck injury he sustained in a Superbike crash at the start of the year is no longer an issue.

Lingering neck problems were blamed for why Schumacher had to abandon his come-back with the Scuderia back in the summer, when he was lined up to stand in for the injured Felipe Massa.

Indeed fitness might be the only stumbling block now, as Schumacher himself recently told Ferrari president Luca di Montezemolo that there was 'a very, very, very strong possibility that he will drive for Mercedes' in 2010 [see separate story - click here].
