The 20-year-old scored on his Liverpool debut last night.
Speaking to Liverpool's official website, manager Jurgen Klopp has said that was "nice to see" new boy Marko Grujic celebrate his debut goal so passionately in Wednesday's 5-0 friendly win at Fleetwood Town.
The Reds continued their pre-season preparations by thumping Fleetwood in a ruthless showing at Higbury, with Grujic, Ben Woodburn, Lucas Leiva and Roberto Firmino - who scored twice - among the goalscorers last night.
But the 20-year-old looked especially pleased with his strike; not because of the quality of the goal, which was a neat finish from 15 yards or so, but perhaps because of the complications in receiving his work permit.
Grujic -who also won a penalty which Danny Ings missed - joined Liverpool in January but was loaned back to the club until this summer.
As a result, he was ineligible to make his debut against Tranmere Rovers last week, but that problem has now been rectified and the young midfielder looked delighted.
"He scored a goal in his first game in the first situation – it’s a dream," Klopp told Liverpool's official website.
"You saw it, in a friendly game not often a player celebrates like him but obviously it was a big moment. It was nice to see."
Klopp's boys get their Premier League campaign off to a tricky start by visiting Arsenal on August 14.
