Sep.19 (GMM/Inautonews.com) Nearly half of all German sports fans think Michael Schumacher should return to retirement, according to a survey.

Citing the German market research company Promit, SID news agency said 47.2 per cent of respondents would advise the seven time world champion against signing a new agreement to stay in formula one beyond his 2012 contract.

In contrast, just 32.2 per cent said the Mercedes driver should stay in 2013, with 8.5 per cent advising a move to the German touring car series DTM to reunite with his brother Ralf.

As for the 42-year-old German himself, Schumacher insists he has not decided what to do.

“I will definitely be here (in F1) next year,” the German is quoted by the Kleine Zeitung newspaper.

“Then we will see what happens.”

Meanwhile, 62.7 per cent of those surveyed tipped Sebastian Vettel to wrap up the 2011 title before the last grand prix of the season in November.
