British former professional tennis player Greg Rusedski has made his thoughts known regarding Rafael Nadal ‘s retirement after watching his warmup session at the Six Kings Slam in Riyadh, Saudi Arabia. The exhibition tournament is Nadal’s first event since the Paris Olympics in August.

Nadal has been away from the court for the majority of this season, despite his comeback in January. The Spaniard kicked off his season at the Brisbane International but suffered an injury that forced him to withdraw from several tournaments. He returned to the court during the clay season at the Barcelona Open.
