It was a big moment for the lifelong Liverpool fan and season-ticket holder, and the sight of him receiving a hug from Klopp on the touchline was a heartwarming one.
“I thought it went well. There wasn’t much [more] I could have done really in the 10 minutes,” Morton told LFCTV.
“I came on, I tried to control the game.
“He told me to control the game, calm it down a bit, get everyone on the ball, get playing, show what I’ve got.
“And I think that’s what I’ve done a little bit, I feel like I’ve got plenty more to come and hopefully I can showcase that soon.”
Morton’s hunger for minutes after that first taste of Premier League football could be built upon in the coming weeks, with James Milner, Curtis Jones, Naby Keita and Harvey Elliott still working their way back from injury.
That would bring another first for Morton, who is yet to play in the Champions League, and would serve as a natural progression as he looks to cement himself as a first-team option.
“I’d love to,” he said when asked if he is hoping for minutes against Porto. “Let’s see what happens!”
He reflected: “It’s a different feeling to any other feeling, especially your boyhood club, as everyone will know, being a fan all my life and now stepping on the pitch.
“It felt surreal, but that’s where I want to be, so that’s where I’m going to push to be.”
