Unfinished business. The two words in Tom Brady's un-retirement statement that told you all you needed to know.
The GOAT is not satisfied with winning seven Super Bowls and dominating almost ever quarterback statistic in NFL history - he wants more.
Sporting legends often do and that's why Brady will return to the league for a 23rd season in September when he'll have just turned 45.
Cristiano Ronaldo of all people helped to break the news, asking Brady if he was done when the two met on the pitch at Old Trafford after the American had watched Man Utd beat Spurs.
The look, the shrug, the entire response suggested Brady was not done with the NFL just yet - and confirmation came soon after.
"These past two months I've realized my place is still on the field and not in the stands," Brady said on Twitter.
"That time will come. But it's not now. I love my teammates, and I love my supportive family. They make it all possible. I'm coming back for my 23rd season in Tampa.''
Brady still capable of winning it all
Brady was retired for just six weeks when he decided that it just didn't sit right and that he had to go and suit it up again with the Tampa Bay Buccaneers.
Head coach Bruce Arians had never fully closed the door on a possible Brady return and the way his career 'ended' meant a return was always a possibility.
The Bucs went out to eventual Super Bowl winners the Los Angeles Rams in the playoffs, but only after Brady had engineered another fabulous comeback to tie the game late on.
Matthew Stafford then won the game at the death for the Rams, but Brady showed that he could still mix it with the best of them - just as he had done all season.
Despite being 44, Brady led the league in passing touchdowns, passing yards, completions and attempts, showing that he could still throw the ball at an elite level.
And his arm could handle a full season of throwing the ball - a lot!
Brady has won four of the last eight Super Bowls, winning it every other year, and with Tampa Bay now busy assembling as strong a squad as possible to support him, there's no reason why they can't make a deep run again.
Wouldn't it just be like Brady to also add the records for shortest NFL retirement and greatest comeback to his CV.
