Liverpool fullback Trent Alexander-Arnold feels his move into midfield last season was a huge development in his career.
Manager Jurgen Klopp made the switch with team flagging at the time.
And Alexander-Arnold recalled: "When the manager showed me the inverted role, I saw it as an opportunity to show I can play in the middle of the pitch.
"You might get one game, it doesn't work and you play the rest of your career at right-back. There's nothing wrong with that.
"But I felt there is more to me playing in the centre of the pitch and saw that as my opportunity to show people what I'm capable of doing. I felt I could dictate and control from right-back, but this was another dimension to my game. How could I evolve? That was what I was searching for. An evolution for me.
"I don't actually know what my best position is, though. It depends on the set-up. For Liverpool, as a full-back I have the freedom to get into central areas and to create from the right-half space and get down the touchline and put crosses in, create chances and get assists over the last five or six years.
"The set-up at England is different for what the manager wants from full-backs. Although technically it's two different positions on the pitch, I think both systems allow me to get in the same positions. Having a licence to get the ball, dictate the game, control the tempo is the most important thing for a player like me. It's not so much if I'm a full-back or midfielder. I'm a player who needs to get on the ball and wants to orchestrate the whole game."
