Mercedes man Michael Schumacher is adamant he still has what it takes to succeed in F1.

The German, who is statistically speaking the best ever driver in the history of the sport, returned last year after three years in retirement.

He had a difficult season and was outperformed by his team-mate, Nico Rosberg. But despite celebrating his 42nd birthday at the start of last month, the seven-time world champion reckons he is still young enough to battle it out with the likes of Sebastian Vettel, Lewis Hamilton and Fernando Alonso.

"Certainly it is not possible to turn back the biological clock," Schumacher told Germany's ADAC Motorwelt magazine.

"It is a fact that I am not absolutely the same now as I was 10 or 15 years ago. But as to whether I am still good enough, I would say yes.

"This season, I think we can aim for the podium and why not some Grand Prix wins too."

Meanwhile, Vettel, who won the F1 drivers' title for the first time last year, also reckons his fellow countryman will do much better in 2011.

"I always see him as a role-model and I think he is capable of achieving something big this season," added the Red Bull Racing #1.

"I hope that it will not be too big, if he is second in the 2011 championships, that would be okay for me!" he joked.
