According to two-time Grand Slam champion Marat Safin, Rafael Nadal and Roger Federer aren’t getting the kind of competition they should be from younger players.
“If Federer and Nadal are still winning I think there’s something wrong,” Safin told the Independent.
“Federer and Nadal are great players but they’re getting older.
After that, Nadal and Federer kept winning, while Britain’s Andy Murray and Switzerland’s Stan Wawrinka eventually won three Grand Slams each.
Just two other players have won majors since then Argentine Juan Martin del Potro at the US Open, and the Croatian Marin Cilic also won at the US Open.
