Lambs to the slaughter - analysis
BBC tennis correspondent Russell Fuller at Roland Garros
There are three, maybe four, players that could possibly beat Nadal.
Stan Wawrinka is his biggest worry. He has the ability if he is on his game to play the most extraordinary tennis on this surface.
Of course you can't discount Novak Djokovic or Andy Murray and then Dominic Thiem who beat Nadal this year.
Everyone else are lambs to the slaughter when they go out to play Rafael Nadal.
