Serena Williams took inspiration from the "unbelievable" Tom Brady as she cruised into the second round of the Australian Open with a "vintage" performance.

Brady made yet more history on Sunday, the most successful player in NFL history winning a seventh Super Bowl as the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9.

The incredible Brady, 43, showed age is no barrier, throwing three touchdown passes – two of which were scored by his long-time friend Rob Gronkowski – and completing 21 of 29 throws for 201 yards.

Brady did now allow any interceptions as he picked up the MVP award at Raymond James Stadium.

Williams started her quest for a record-equalling 24th grand slam singles title with a 6-1 6-1 defeat of Laura Siegemund on Monday, then paid tribute to her fellow American Brady.

She said of his exploits: "It's unbelievable. I just was watching as much as I could to see. My only word is it's unbelievable. I kept saying: 'This is unbelievable, this is unreal'.

"You can't say it was the system he was at formerly [the New England Patriots]. It's definitely Tom Brady, he's Tom Brady. He's amazing."

Brady banished everyone from his house in the days leading up to the Super Bowl so he could fully focus on inspiring the Buccaneers to victory, but the 39-year-old Williams said she could never do the same as she would not want to be separated from her daughter, Olympia.

"I would not be able to go function without my three-year-old around," Williams said. "I think I would be in a depression.

"We've been together every day of her life, so... Is that healthy? Not at all! Not even close. But every single day I just want to be around her. It's great. Everyone's different.

"I can totally understand why he would banish because if I had the strength to do it, I would too.

"I could see it's definitely a distraction, especially every year that I've played except for the past few months, I finally am starting to get better at it. The first two and a half years was very difficult. I wasn't strong enough to do the banishment."

Williams, who will face Nina Stojanovic in the second round at Melbourne Park, was delighted with the manner in which she swept Siegemund aside and had no issues with her shoulder after withdrawing from a pre-tournament event citing an injury problem.

"This was a good start. Definitely vintage 'Rena'. It's definitely good. I think I'm pretty good at pacing myself in a grand slam," she said.

"I was happy just to get through it. Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So, it felt really good.

"Last year was very crazy for the world, and to be able to do what I love and to be able to come out and compete and play at a grand slam, after the last 12 months, it makes me appreciate the moment even more."

Tom Brady claimed a seventh Super Bowl crown after leading the Tampa Bay Buccaneers to their first Lombardi Trophy since the 2002 season with a dominant victory over defending champions the Kansas City Chiefs.

Tampa Bay Buccaneers quarterback Tom Brady is aiming to surpass "idol" Michael Jordan by winning his seventh Super Bowl ring.

No player has won more Super Bowl titles or appeared in more NFL showpieces than six-time champion Brady, who will lead the Buccaneers against reigning champions the Kansas City Chiefs in Super Bowl LV on Sunday.

Chicago Bulls and NBA great Jordan also won six championship rings during his Hall of Fame basketball career.

As Brady stands on the cusp of a seventh Lombardi trophy, the 43-year-old superstar told reporters on Monday: "Michael [Jordan] is one of my sports idols.

"I think he's pretty incredible and for me it's just about being a part of great teams.

"To have the opportunity to play in this game means a lot to me. It's a lot of commitment and sacrifice by a lot of guys.

"Obviously we're one game away from the ultimate goal in this sport. I've been a part of that ultimate goal six other times so they are all different and have all meant something a little different to me. They've all been unique in their own way. 

"It would be cool to accomplish it this time, I don't compare them to the other times, those were all magical moment of my life and no one can ever take those away from me.

"Hopefully we can finish this season strong and win a Super Bowl. That's why we're here, that's why we're playing, to make for a really magical season for us."

Brady – who will go head-to-head with reigning Super Bowl MVP Patrick Mahomes in Super Bowl LV on home soil – has more playoff wins since turning 35 (17) than any other quarterback has in his entire career, per Stats Perform.

Tampa Bay's Brady became the third player all-time with three-plus touchdown passes and three-plus interceptions in a conference championship game, joining Joe Montana (1981 NFC Championship) and Mark Malone (1984 AFC Championship), after the Buccaneers topped the Green Bay Packers in the NFC decider.

The 31-26 win in Green Bay was also the fourth time Brady has thrown three-plus interceptions in a playoff game, and his teams are 3-1 in those matchups (most such wins all-time) – his sides are 0-9 when he has three-plus interceptions in a regular-season game.

It was the 20th occasion Brady has led his team to 30-plus points in a postseason game – no other player has even half that total (second is Troy Aikman with nine). Brady's teams are 18-2 in those games.

Brady will feature in his 10th Super Bowl – the next most by a player is six by Mike Lodish and Stephen Gostkowski, after the Buccaneers became the fifth team all-time to win three road games in a single postseason.
