Tuchel gave his reasoning for omitting Alexander-Arnold from his latest squad, insisting he was aware of the defender's qualities but adding that it was a conscious decision to select other right-backs ahead of him.
He said: "I know very well what Trent can offer us. I played many times against him and suffered when he played against my teams with Liverpool. So I know very well about his strength and what he can give.
"But at the moment it is like we have evidence how good we were in September, October, November, and the players who are in camp for right full-back, they have to push for their ticket, they have to compete, they have to show again that they deserve this.
"It is a sporting decision that we stick with [Jarell] Quansah, with [Tino] Livramento and with [Djed] Spence."
