Jürgen Klopp's personal intervention has helped to ensure Marko Grujic can get his Liverpool career underway, after he was successfully granted a work permit on Monday.
The 20-year-old signed for the club back in January but only joined up with his new teammates over the weekend in pre-season training, having seen out the second-half of last season with boyhood club Red Star Belgrade.
Helping them to the Serbian title, £5.1 million Grujic moved to England recently but needed a work permit in order to play for the Reds after failing to qualify under the regulations.
He had a hearing in a Manchester hotel, with a three-man panel from the Football Association and due to Klopp's presence, and also the glowing endorsement he provided of Grujic's quality, the process was concluded successfully.
The Reds boss explained in his testimony the importance to which Serbia international Grujic will have to his side in 2016-17, convincing the FA board to allow the player to start his Merseyside career.
The club announced that the player will take the No.16 shirt, but he could be forced to wait for his first appearance - with the Liverpool Echo suggesting that Grujic will have to leave the UK and later re-enter for the work permit to officially go through.
Grujic could be forced to wait for Reds friendly debut
That could mean Grujic - who was an important member of the Serbian side that won the U20 World Cup in New Zealand last year - is unavailable for the Reds' opening friendly at Tranmere Rovers this Friday.
Klopp is already without a number of first-team midfielders, given that 13 players have been involved at Euro 2016 and Copa America over the last few weeks.
But Sadio Mane, Loris Karius and Joel Matip could all make their bows for Liverpool having also joined up with the squad for training at Melwood on Saturday.
Another who was present, 19-year-old forward Ryan Kent, could be set to seal a season-long loan to Championship outfit Barnsley according to reports from the Daily Mail.
Kent, who spent a fruitful spell with Coventry City last season, made his first-team debut back in January but has yet to establish himself in Klopp's first-team and will therefore be sent out to continue his progression in the English second-tier.
Grujic, who would have had to be sent out on loan had he not been granted a work permit, will likely make his debut - although not his competitive one - against Fleetwood Town on July 13.
