He told ESPN: "His right foot is ridiculous. It's ridiculous. I mean, I enjoy highlight reels. Sometimes more, sometimes less, but with Trent Alexander-Arnold [his] highlight video is insane; because you don't need goals, it's just the passes. You just watch the passes, how is that possible? I could pass the ball myself but not like that. I remember that Trent was a brilliant kid but physically not ready so we always had to take him off after 60 minutes - all fine. But he developed in that department obviously as well."
