Felix Auger-Aliassime knows full well that turning up with the same old stuff won't be enough if he is to find a way past title favourite Daniil Medvedev in the Australian Open quarter-finals on Wednesday.
It didn't work at the ATP Cup a couple of weeks ago, it wasn't effective in the US Open semi-finals last September and it won't cut the mustard this time either.
Nick Kyrgios and towering American Maxime Cressy have each taken a set off Medvedev in the early rounds at Melbourne Park, without being able to maintain the rage for long enough against the metronomic Russian.
The ninth-seeded Auger-Aliassime boasts different weapons to both the enigmatic Kyrgios and the US serve-volleying expert.
"I would say the first time we played (at the 2018 Canadian Open) was a while ago and we are both very different players," said the rising Canadian star.
"But the last two times, one was last week or two weeks ago, and also the US Open, so yeah, I need to try to change things up.
"I have nothing to lose, to try and do something differently or to play good and then to dig deep.
"I can try to mix up things as much as I want.
"The reality is he's the best player almost in the world now.
"I need to play a great match. I need to be able to give a great effort both mentally and physically to go through."
The Canadian No.9 seed can at least draw encouragement from his four-set win in the fourth round against Croatian Marin Cilic, as the 2014 US Open champion had won their previous three encounters.
"It feels really good to beat a player you have lost to in the past," said the 21-year-old Auger-Aliassime.
"It also proves to yourself that you have done improvements, you have become a better player."
Medvedev lost his cool on a number of occasions in his fourth-round win on Monday, later apologising for slamming Cressy's style of play as "boring".
"I was quite mad because of a few things," said Medvedev, who won his first grand slam title last year at Flushing Meadows after beating Auger-Aliassime in the semis and world No.1 Novak Djokovic in the final.
"To be honest, I'm working on myself, and that's why I managed to win and still kept my composure, as much as I could, because sometimes I go much crazier than I did today."
The winner will play either Greek No.4 seed Stefano Tsitsipas or young Italian sensation Jannik Sinner in the semis on Friday.
