While he made his Reds debut in October 2016, it was the 2018 World Cup in Russia where he formed a strong relationship with midfielder Henderson.
In an interview with Red Bull, Alexander-Arnold said: “Hendo was big. I never really had an amazing bond with any of the lads because I've always been quiet, but he just made me comfortable.
“He made me not be afraid to make mistakes and not feel I'm not as talented as the other lads.
“After that I wasn't overthinking. I'd take more risks and by doing that I became a better player."
