India enrolled a superstar follower for their World Cup clash against Pakistan on Sunday in the shape of tennis legend Roger Federer.

The Swiss great, a winner of 17 Grand Slam titles, was pictured on his Facebook page admiring an Indian team shirt which he had unwrapped from a gift box.

"Dressing up for a Gentleman's game today. #BleedBlue," wrote the 33-year-old.

Federer would not be a whole outsider to cricket as his mother Lynette was born in South Africa, a country which has high hopes of a first World Cup title in the sport.

Federer and Indian batting legend Sachin Tendulkar are known to be close with the 'Little Master' a regular visitor to Wimbledon each year to see the Swiss play.

Virat Kohli, who made a century for India on Sunday, also met Federer in Sydney in January, describing the tennis player as an "absolute legend" in a captioned picture he posted on his Twitter site.
