Wilson, aged just 18, is a full international, virtue of winning one cap for the Welsh, but predominantly features for the U21 squad under the guidance of Williams.
In a key clash against Armenia in a 2017 European Championship qualifier, the talented winger topped off a superb display by firing in a last-minute winner to hand his side a 2-1 victory.
Speaking after the game, Williams was impressed by Wilson’s ability to overcome his lack of physicality and spoke highly of his prospects of featuring in the upcoming U21 championship.
“I don't like to single out individuals as it's a team effort, but Harry is a young man with great talent,” Williams was quoted as saying.
"Physically, he is one of the smallest players on the pitch at this level and he is young enough to play in the next U21 competition.”
"But he can nullify the physicality of other players by getting into spaces and running with the ball, and showed wonderful composure to take that chance and get us those two extra points against Armenia."
The Reds youngster is currently out on loan at Crewe Alexandre, though opportunities have so far been limited at Grestly Road, with Wilson making just five appearances for the club.
The Wrexham-born ace has a bright future in the game, though, with his low centre of gravity and intelligent movement allowing him to overcome the fact he isn’t the most physically imposing.
Regarding his style of play, some could argue he is tailor-made for a Jurgen Klopp team, as the popular German coach likes to deploy a high-pressing style with plenty of off-the-ball movement.
