According to the German newspaper Bild, the 66-year-old - who famously took 20 per cent of Schumacher's huge formula one earnings - is seeking a patent for a soft-drink can design that can be re-sealed once it has been opened.

"I am convinced that in ten years everybody will be using it," he said, adding that he wants to "conquer" the market that involves the sale of 250 billion cans every year.

"With this I can make more money than I did with Schumacher in 15 years of formula one," he boasted.
