Rafael Nadal insisted he still "feels pressure" and is "only human", after battling back from a set down to beat Diego Schwartzman yesterday and set up a French Open semi-final clash with Juan Martin del Potro. The 10-time champion was much-improved under the sunshine on Court Philippe Chatrier after finding life difficult the night before, clinching a 4-6, 6-3, 6-2, 6-2 victory over dogged Argentinian Schwartzman on his fourth match point.

It is the 11th time the Spaniard has reached the French Open last four, becoming only the third man in history to achieve the feat at a Grand Slam tournament, after Jimmy Connors at the US Open and Roger Federer at Wimbledon and the Australian Open. "I don't have any obligation to win, first thing. Second thing, if you don't feel the pressure, it's because you don't love the sport," said Nadal, who has never failed to win the title in Paris after reaching the semi-finals.
