With Joe Gomez ruled out, Alexander-Arnold produced an eye-catching display at right-back in Liverpool's 2-2 draw with Spurs.
The 19 year-old did an excellent job of keeping both Ben Davies and Dele Alli quiet on Tottenham's left hand side and also provided a threat going forward, supporting Liverpool's lethal front three.
In fact he impressed so much that Jamie Carragher had this to say about the current England Under-21 international:
"Listen, this lad - I've said it before - is going to be a future England full-back," Carragher told Sky Sports. "He just looks the part."
His performance and those glowing words of praise have caused bookmakers to slash his odds to make the plane to Russia from 14/1 to 5/2.
Joe Gomez, ruled out of the Tottenham game with a knock, has impressed for Klopp's team this season and will himself be hopeful of going to Russia at odds of 6/4.
He has been at fault for a couple of goals in recent fixtures though and that could mean Alexander-Arnold cementing his place in the first eleven and really pushing his case to Gareth Southgate from now until the summer.
Oddschecker spokesperson, George Elek: "Kyle Walker looks to have the starting berth at right-back for England nailed down, but his deputy looks sure to come from Liverpool.
"Both Gomez and Alexander-Arnold look top options, although the latter could get the nod if he manages to keep his spot in the team with more performances like yesterday's."
