Andy Murray has recorded his first win of the year over a top 20 opponent at the Madrid Open.
But the Scotsman says he “shouldn’t have a chance” of getting past world number one, Novak Djokovic, in the third round.
Murray got the best of Denis Shapovalov in a three set thriller, winning 6-1 3-6 6-2.
He now faces Djokovic in the last 16.
“He’s obviously No 1 in the world [and] I’m playing with a metal hip, so I shouldn’t have a chance,” Murray said in his post-match interview.
“I thought about it a little bit at the beginning of the third set. I didn’t know if I was going to get the chance to play matches like that again.”
Murray added: “In theory I shouldn’t have a chance in the match, but I’ve put myself in a great position.
“I worked extremely hard in the last five or six weeks to get myself here and it’s a fantastic opportunity to play against him again on a huge court in a big tournament. I’ve got my game in good shape.
“I’ll have a fantastic attitude in the match, give it my best and see where I’m at.”
It will be the 37th time the two players have gone head-to-head in their career.
