Scott Brown lives for the Old Firm derby.
Now into his 11th season at Celtic having joined in 2007, the 32-year-old has played against Rangers countless times and thrives whenever he does.
He epitomises the two clubs' rivalry with his passion and tough-tackling style, which Celtic goalkeeper Craig Gordon believes inspires his teammates.
"Scott's always good, he's always got a good thing to say, whatever game it is," said Gordon ahead of Saturday's derby, per the Daily Record.
"He's always there to make sure everybody's ready to go, even at that last moment before kick-off. He can be quite animated, especially in these games.
"Scott can take a bit longer with his talk, depending on what he has to say. It gets everybody going and some of his displays in these games have been outstanding.
"When he gets it right, he can run games. If you see your captain like that then it is something that can inspire the rest of the boys."
It didn't take long for Brown to stamp his authority at Celtic Park when he produced what some would call a 'Scott Brown moment'.
In the video(s) below, Brown launches himself into an aerial challenge with Rangers midfielder Jason Holt to completely flatten the 24-year-old and win the ball.
Then, as Holt walks away, Brown screams at him and turns, shorts rolled up and looking like an absolute lunatic. Check it out.
SCOTT BROWN BEING SCOTT BROWN
There was one other moment in the opening 45 minutes that not many people noticed, but those who did couldn't believe their eyes.
Scott Brown, one of the hardest midfielders in the game, produced a no-look pass. Seriously.
With the scores level at 0-0, the Celtic captain passed back to a teammate and looked the other way. Outrageous.
Brown isn't renowned for his trickery in the slightest, but that didn't stop him from producing a skill usually associated with the likes of Cristiano Ronaldo and Mesut Ozil.
