Andy Robertson isn't one to shy away from confrontation.
When Cristiano Ronaldo appeared to kick out at Curtis Jones during Liverpool's derby clash with Manchester United on Sunday, the fiery Scot was the first Reds player on the scene protecting his teammate.
He's previously clashed with the likes of Lionel Messi and Kyle Walker and was therefore always going to wind up the Man United supporters inside Old Trafford if the opportunity arose.

KLOPP: Liverpool boss sends classy message to Solskjaer after Man Utd thrashing
"Greatest days? I didn't think about it, yet. It's a good day, a really good day and I don't want to be disrespectful," said Klopp.
"I have no idea, but it's a big one. We know that. Obviously, after the game I got told that never happened in the long history of Liverpool; this group always wanted to write their own little chapters for the big, big history book of this club.
"This one was a little one tonight, a little chapter. People will talk about it in the future, 100 per cent, because it will not happen very often, if it happens again at all.
"We saw the game as well and we know we were lucky in two or three situations where United could have scored in the first half. I think they should have scored the first one, but that doesn't make our performance [any less], that's just how it is."
Man United boss, Ole Gunnar Solskjaer, meanwhile, reflected on a difficult day for the Red Devils.

"It's not easy to say something apart from it's the darkest day I've had leading these players and we weren't good enough, individually and as a team," he said.
"You can't give a team like Liverpool those chances, unfortunately, we did.
"The whole performance wasn't good enough, that's for sure. We've created openings, they've had chances and they've been clinical. We didn't take our chances early on and the third goal is the one that decided the game."
