London, Nov. 23 Speculations over Michael Schumacher's Formula One comeback are rife once again, with his manager saying that the seven time F1 champion had spoken with representatives of Mercedes-Benz.

The moment Jenson Button announced his decision to leave Mercedes Grand Prix (formerly Brawn GP) to join McLaren, media reports started suggesting that Button's former team principal, Ross Brawn, had approached Schumacher to replace him, Times Online reports.

Schumacher's long-time manager Willi Weber added a little more fuel to the fire by saying that he was sure that Schumacher had had talks with Dr Dieter Zetsche, head of Mercedes-Benz and Norbert Haug at the Abu Dhabi Grand Prix.

Schumacher's official spokeswoman, Sabine Kehm, said: "My personal opinion has really not changed. I can see lots of tempting things in it for Michael, but I can also see a lot of non-tempting things. I don't know. It is as it was in August [with the Ferrari comeback] when you couldn't tell what was going to happen. Then I was convinced Michael would never come back and, suddenly, all the circumstances were right for him. I still think it is unlikely, but you never know."

Earlier, Schumacher wanted to help out at Ferrari when his friend Felipe Massa suffered serious head injuries in qualifying for the Hungarian Grand Prix.

But that comeback was ultimately thwarted by a neck injury that the German legend sustained while racing a motorbike this year.

Now, the 41-year-old driver has the chance to do a favour for his former technical director at Ferrari in Brawn, who is short of high-quality options in his search for a team-mate for Nico Rosberg. (ANI)
