But Alexander Zverev admits he is the complete opposite to the world No 1 in that regard.
Zverev, ranked third in the world, dreams of one day leapfrogging Nadal in the standings.
The pair are both through to the Rogers Cup quarter-finals after winning their respective third round matches last night and this morning.
After Zverev’s latest victory, the German lifted the lid on his behaviour while explaining how Nadal’s routine does not help his opponent.
“I am very far from a superstitious guy,” he said.
“I think when you’re superstitious, especially on court, you start being readable and you start, you know, kind of being predictable sometimes.
“For example, Rafa (Nadal), he’s superstitious but his superstitions have nothing to do with tennis.
“They’re all kind of away from tennis. They’re never superstitions inside of his game.
“So whether he does it or not, it’s his thing. But when you’re superstitious on the actual tennis court, I don’t think it’s a good thing.”
Following a disappointing Wimbledon campaign, Zverev returned to action early to compete in the Citi Open last week – which he won.
But when asked what he did prior to the Washington DC event, the 21-year-old had a hilarious response.
“The first week or so after Wimbledon I was working a lot on my tan line,” he said.
“I was on a boat in Monaco trying to work on that a lot. Then, after, I started doing physical training. I did 10 days of only physical in Monaco with Jez Green.
“And then, obviously, went to Florida for a few days before Washington and started playing tennis.
“That was kind of my period. And, obviously, I played in Washington. You guys probably heard about that.”
