Novak Djokovic and Stan Wawrinka may give the Australian Open the second-week boost it needs.
Bring on Djokovic-Wawrinka III.
For the third straight year, Novak will meet Stan at the Australian Open.
For the third straight year, may it be a Melbourne Park classic.
The previous two years, the winner has gone on to claim the title.
Importantly, both Djokovic and Wawrinka sealed their places in the semi-finals with impressive victories on Wednesday.
Wawrinka disposed of Kei Nishikori 6-3 6-4 7-6 (8-6), while Djokovic crushed Milos Raonic 7-6 (7-5) 6-4 6-2.
It set up what could well be a memorable Friday night blockbuster.
A classic would give the year's first grand slam a much-needed second-week boost.
All four men's singles quarter-finals were done in straight sets, while only one on the women's side went to a decider.
In the 2013 meeting between the pair, it was 12-10 Djokovic in the fifth " and in 2014 it was Wawrinka who edged the decider 9-7.
Overall, the head-to-head is a rather one-sided 17-3 in favour of the Serbian world number one.
What awaits is an exhibition of shot-making and defensive prowess, the latter particularly from Djokovic's end.
The seven-time grand slam champion has been broken just once this tournament, holding 73 of his 74 service games.
Wawrinka has hit more winners (241-181), with both players' forehands doing most of the damage.
Djokovic has spent an hour less on court than Wawrinka, but neither has been tested enough for it to be a decisive factor.
Wawrinka knows the level he will need to be at to beat Djokovic.
"I think for sure it will be funny to play him again. I will be happy to play him three straight year in a row," he said.
"We had some crazy matches in the grand slam in the past.
"You have to play your best tennis if you want to push him.
"So far I'm playing great. I'm confident with my game. Let's see."
Djokovic believes Wawrinka's self-belief has been decisive in helping him win his maiden grand slam title, as well as last year's Davis Cup with Switzerland.
And he is ready for a physical battle similar to their previous meetings.
"Grand slams are the tournaments where you want to perform your best," Djokovic said.
"I'm sure we both are very much aware of that fact, and it's why we get to play on a high level against each other and we push each other to the limit in a way. It's a very physical battle, as well.
"But I haven't had too many long matches during this tournament. I'm ready for it. I'm going to practice, do a little preparation for that match, try to analyse his game and what I need to do in order to win."
Bring on the battle.
