Rafael Nadal has said that he ‘can't think about’ potential Rogers Cup opponents Stan Wawrinka or Nick Kyrgios before his second-round opener in Toronto.

The world No 1 - playing his first event since losing to Novak Djokovic in the Wimbledon semi-finals - will face either Jared Donaldson or Benoit Paire in his opening round, but could meet three-time Grand Slam champion Wawrinka or Australian favourite Kyrgios in the third round.

Following the withdrawals of Roger Federer and Andy Murray, the pair are expected to be two of Nadal’s closest challengers alongside Novak Djokovic and Alexander Zverev in a star-studded line-up.

Nadal has said that he has to focus on what is in front of him, not what lies ahead in Toronto.
