LONDON — French Open champion Stan Wawrinka feels completely comfortable about his failure to break into the unofficial big four of men's tennis despite winning two grand slam titles.
The Swiss stunned Novak Djokovic in the Roland Garros final this month to collect his second major crown and is seeded fourth at Wimbledon where he began his title bid with a 6-2 7-5 7-6 win over Portugal's Joao Sousa in the first round on Monday.
But people still talk of Djokovic, Roger Federer, Andy Murray and Rafa Nadal as the big four.
"I personally really don't care," Wawrinka told reporters.
