If Roger Federer prepares to take on Novak Djokovic in the men's Wimbledon final, the Swiss knows much more can improve his chances of winning a 21st Grand Slam title than all the hard work has been done.
"This is like a school," the 37-year-old said. "The day of the test, you're not going to read … many books that day. You don't have the time anyhow.
"It's quite clear the work was done way before. It's been a rock solid year (for me) … the stars are aligned right now. From that standpoint I can go into the match very confident."
With eight Wimbledon titles to his name, Federer has every right to be confident.
But Djokovic himself is a four-time SW19 champion, and can match the great Bjorn Borg with victory for a fifth crown.
More importantly, the Serbian got the better of Federer in the final here in 2014 and 2015.
"We all know how good he is anywhere, but especially here," Djokovic said of his rival.
"This surface complements his game very much. He loves to play very fast. Takes away the time from his opponent. Just doesn't give you any same looks.
"He just rushes you to everything. So for players maybe like Nadal or myself that like to have a little more time, it's a constant pressure that you have to deal with.
"I've been playing with Roger in some epic finals here for a couple of years, so I know what to expect. Of course, I'm going to be excited and nervous and everything that you can think of.
"I'm going to control my way in some way and be able to portray my best tennis in a balanced, hopefully, state throughout the match."
