Cristiano Ronaldo produced a stunning performance last night in Portugal and Spain's memorable 3-3 draw at the Fisht Olympic Stadium.
The Real Madrid star has been inconsistent in previous World Cups, but at this summer's tournament in Russia, he looks up for it.
Late on, he cancelled out any chance of Spain collecting the three points with a superb free-kick to take the game level and earn himself a hat-trick.
But it was the first goal that had people talking, not least because of Ronaldo's strange celebration.
After being taken down inside the box early on, he unmistakably buried the following penalty.
He celebrated with the classic SIUUU move - a celebration which still looks absolutely epic - but then he stroked his chin several times.
And supporters across social media believe that this was a reference to being the GOAT - the greatest of all time.
Lionel Messi might have something to say about that, Ronny.
After the match, Manchester United boss Jose Mourinho heaped on the praise for the 33-year-old. He said to Russia Today: "He has this little touch, this little extra feeling, and the goal is fantastic.
"He knew it was the last chance and that's what I really admire.
"There are players for some matches, there are players for every matches and there are players for special matches."
Well, if you like him so much, Jose, you could give Man United fans what they've all been waiting for...
Fans would love to see the GOAT at Old Trafford.
