The Dane was appointed in early September in one of the most surprising deals of the summer in a bid for the Reds to gain an advantage over their rivals from breaks in play.
And his short stay has proved successful enough to merit an extended deal at the club — which will see him Anfield-bound until the end of next season.
The 42-year-old himself said that his role was the "weirdest job in the world" after signing with the Reds.
But the move will come as good news for Liverpool and England fans alike as there has been a clear benefit from the specialist's presence.
In Sunday's Three Lions comeback against Croatia, Joe Gomez used what he learnt from the Dane in practice and remarkably produced an assist for Jesse Lingard from the touchline.
After the game, Gronnemark told BBC Sport: "Gomez's throw-in against Croatia showed it is a dangerous weapon for Liverpool and England.
"I think it won't be used very often, but the opponents have to think twice before they put the ball out of play."
Gronnemark, who also works for FC Midtjylland and AC Horsens and in the Bundesliga, holds the world-record for the longest throw ever recorded at 51.33 metres.
And he has earned praise from former players too for his work.
Speaking to BBC Radio 5 live's Monday Night Club, Ian Wright said: "I saw Joe Gomez take some really good throws for Liverpool that I had not seen him do before, he was fizzing it in there.
It looks like he [Gronnemark] has taught him something. You have to say Liverpool will benefit from that."
