Iga Swiatek admits that, like Pedro Cachin, she would also swap shirts with Rafael Nadal following his Madrid Open exit.

The 22-time grand slam champion's farewell appearance at the clay-court ATP Masters tournament, which he has won five times, was ended by a straight-sets defeat to Jiri Lehecka.

Nadal had beaten Cachin in the last 32, with the Argentine subsequently asking his idol for his shirt as a memento following their clash.

Although Swiatek has never been tempted to follow suit with an opponent, the world number one acknowledged she might make an exception for the Spaniard.

"If I would play against Rafa, for sure I would ask for a T-shirt," she laughed.

"For sure, he was a huge inspiration. When I was younger, he was basically the only player I looked up to, but not because of his game on clay - more because of the way he is off the court and how he never gives up, and also his mentality."

Swiatek is through to the semi-finals in the ladies' draw after recovering from losing the opening set to defeat Beatriz Haddad Maia 4-6 6-0 6-2.

The Pole, who will play former US Open runner-up Madison Keys in the last four, equalled Serena Williams and Maria Sharapova as the fastest player to reach 25 WTA 1000 wins on clay, doing so in just 29 matches.
