London - Roger Federer is not bothered by superstition as he starts the quest for a record-equalling seventh Wimbledon title while Switzerland tries to keep a dream alive in South Africa at the Soccer World Cup.
Even the world's best on grass admits that the Swiss success on the pitch is something special after starting with an upset victory last week over mighty Spain.
"I'm not superstitious, this is something very historic for Switzerland," said the tennis tournament's top seed. "We obviously haven't had the success on a soccer level that maybe we've had in tennis over the last 20 years.
"Obviously this was a huge match - I watched it, of course."
But Federer said he didn't make a point of getting in touch with friendly Spanish rival Rafael Nadal after the footballing upset.
"I'm not the type of person who rubs it in. We know the bad times can come by very quickly. But obviously after a match like this, you're allowed also to start dreaming that you could go much further in the competition," he said.
