Tuchel, who has made clear his love of the physical nature of English football alongside his want of a solid backline referenced Jarrell Quansah, Djed Spence and Tino Livramento as the players in front of Alexander-Arnold.
And although predominately a centre-back, Aston Villa’s Ezri Konsa played at right-back in the comfortable win over Wales in October and is an option there too.
“A slightly different profile,” Tuchel said when asked by BBC Sport about what the other players bring.
“It’s not what Trent cannot offer us. I know very well what Trent can offer.
“I suffered when he played against my teams with Liverpool. I know very well about his strengths and what he can give.”
Livramento played the second-half of Newcastle’s 7-2 defeat by Barcelona in the second leg of their Champions League tie on Wednesday, but he has already impressed the England boss.
Tuchel is big on players having “credit” for what they have previously done for him and Livramento played in England’s 5-0 away win against Serbia, arguably the most impressive performance since he took charge.
“It is a sporting decision that we stick with Quansah, Livramento and Spence who all can play in camp in the right full-back position,” added the German.
“We have evidence with how good we were in September, October and November and the players who are in camp have to push for their ticket. They have to show again that they deserve this spot.”
