Grace Robertson wrote a good blog post yesterday that English fans are too hung up on what position is listed next to a player on the TV graphic and what that means more than what a player is actually doing. It's a paid article so I won't copy/paste it here but this small snippet:
The Italians use terzino, which has a pretty complicated history. Antonio Gagliardi, assistant coach at Juventus, has talked about Alexander-Arnold as an example of terzini-registi, essentially “playmaker full-backs” (though a regista tends to more specifically mean an Andrea Pirlo-style deep-lying playmaker). “A player is no longer tied to a fixed position”, Gagliardi explained. “We identify them by the jobs they perform, not the position they play.
“As systems become more and more fluid with rotations and interchanges, players are moving around the pitch and doing jobs that reflect their skill set. Alexander-Arnold can be Liverpool’s playmaker because he has a talent that’s way above average for a full-back.”
He's listed as a RB but when this LFC team was at it's best Trent did almost nothing on the field that you would quantify as what a RB would typically do. We defended with a 5 of the 2 CB's and 3 midfielders and we attacked with a 5 of Trent/Robb and the front 3. This basic blueprint led us to heights we've never seen. I've stated over and over in this thread and elsewhere that 20 years ago he's David Beckham and these conversations don't even exist. People just need to get over this crap of him being listed as a RB. Yes he defends in that space when required but in an ideal LFC game he would never do it.
