Former Olympic gold medalist Marc Rosset tells Switzerland’s Tennis Magazine that men's tennis is less competitive than it once was.

The big-serving Rosset played during the 1990s, winning the gold medal at the 1992 Barcelona Olympics. He also reached the 1996 Roland Garros semifinals.

"Tennis has been reduced to three or four players: Nadal, Federer, Djokovic and to a lesser extent Murray,” he said. “They bring in the money and the audience. All the others don’t matter. Like [Stan] Wawrinka in 2013 in Basel, he won his first-round match, there were very few fans at the tournament during the last 10 years. Federer outshines everything."

The 43-year-old Swiss said that back in his day there were more players who had chances to win majors, which he believes made the game more interesting.

“That was much more exciting,” he said. "The fact is players are becoming increasingly similar. Overall, it scares me what has become of the men's tennis. It needs more variety. "
