Here's what the Beeb says:
Michael Schumacher will make a shock return to Formula 1 to replace injured Ferrari driver Felipe Massa, news agencies are reporting. The seven-time world champion retired at the end of 2006 but has agreed to drive at the European Grand Prix. ... Schumacher has been a team advisor but on 23 August will race an F1 car for the first time since April 2008.
If the news turns out to be true, I for one will be hoping that Schumacher will be effortlessly left behind in a cloud of dust by the current bunch of drivers. I couldn't stand him at the best of times. And there are better drivers around to stand in for Massa
