Liverpool manager Jurgen Klopp has revealed he had no doubts regarding the use of Trent Alexander-Arnold as an inverted full-back.
The right-back has been in central midfield when the Reds have the ball in recent matches.
Such a change has proved a masterstroke, with the Reds destroying Leeds United 6-1 on Monday with Alexander-Arnold in fine form.
“In each position he played for us, Trent was always a super-important player," Klopp told reporters.
“This now slightly advanced role suits him in the moment really well.
“It's good, it's a challenge for everyone else to cover the spaces when we lose the ball theoretically, but with him there we didn't lose that many balls, which was helpful as well.
“But it's not written in stone (that we stick with it). Why should we? He can play in different ways and how he played the last two games was really, really good, that's true."
He continued: “(We worked on it for) a week but it's not the first time that we play it like that. We have a lot of situations. It's slightly different but not as different as we had it in some other games when Trent was all the time in the right-back position or higher up.
“We had a week. That is absolutely okay. Trent is a smart player but it is more about how we set it up around Trent. That he can play the position was never in doubt but you have to set it up around him because there are moments when we lose the ball, we have a different formation.
