We start with tennis, and this weekend will see the third round and the beginning of the fourth round of the men's and women's singles at the Australian Open.
As the fields start to thin, we figure to see a lot of both experienced players and up and coming ones putting in genuine bids for the year's first Grand Slam championship.
One such up and coming player is 24-year-old Czech Karolina Pliskova.
She was a semi-finalist at the Australian Open and Wimbledon last year, and the number five seed has made her way through to the third round in melbourne this year.
And if she wins her third round match against Latvian Jelena Ostapenko, she could face Australia's Daria Gavrilova in the fourth round.
But Pliskova isn't underestimating Ostapenko, and says she needs to keep getting better if her stay at the tournament is to keep getting longer.
"I've played her in Cincinnati in the first round, so I know a little bit about her. But it's the third round (here), so she's won two matches as well. So I'm expecting a tough match. But hopefully I can still improve my level and a play a little better. And hopefully it's going to be enough."
In cricket, the Sydney Sixers will be guaranteed a spot in the semi-finals of the Big Bash League if they defeat the Melbourne Stars on Saturday night.
It will be the last game of the home-and-away rounds of the Twenty20 league.
Sixers batsman Nic Maddinson says, for his side, the make is like a finals match before the actual finals.
"We need to go out and win and finish as high as possible. Our net run rate isn't that great. So we are looking to win, and win well. In a way, if we want to look at it, this is our Grand Final. So everyone's looking forward to the challenge."
The Brisbane Heat are top of the table and the only team who have confirmed a spot in the four-team finals series.
Six teams will be fighting for the other three spots, with the Adelaide Strikers and Sydnery Thunder already eliminated.
The Brisbane Heat play the Melbourne Renegades on Friday night, and the Perth Scorchers play the Hobart Hurricanes on Saturday afternoon, before the Stars-Sixers game.
In football, Sydney FC will be looking to stay undefeated atop the A-League ladder.
They host Adelaide United on Friday night.
Adelaide has won just two of their fifteen A-League matches this season.
But Sydney midfielder Josh Brillante says despite that, there will be not let-up from his side.
"We take every team quite seriously. It's always a tough match. So...take it step by step and week by week...and focus on what we need to do. And if we do that, we'll come out with the result."
And in the English Premier League, the glamour match of the weekend sees Manchester City taking on Tottenham.
Tottenham are in second place, seven points behind frontrunners Chelsea.
Manchester City have been a disappointment so far this campaign, their first under coach Pep Guardiola.
They enter the weekend in fifth place on the ladder, and lost four-nil to Everton in their last match.
That means plenty of pressure on the much-hyped Guardiola.
But a former Manchester City man who knows Guardiola well has faith in him.
David Villa played under Guardiola at Barcelona, enjoying much success.
He says his former boss will turn things around for his current team.
"It's difficult to win, and he wins almost always so it's normal to have difficult periods in the team but he's great and I think he has a methodology and he has a very good coaching staff for change. Manchester City is in a different period right now but I believe they will change the situation soon."
Frontrunner Chelsea will be looking to extend their lead atop the table when they host relegation-threatened Hull.
