When Liverpool announced that they were to hire Thomas Gronnemark as a throw-in coach, many made light of the appointment.
Gronnemark was brought into Melwood in order to improve the technique of players such as Trent Alexander-Arnold, Joe Gomez, Alberto Moreno and Andrew Robertson.
Robertson, who is quietly becoming one of the best left backs in the game, has already expressed his appreciation for the introduction of the Dane to the Reds' coaching set up:
The one negative he seen was we surrendered possession when we had throw-ins.It is effectively like a pass. He looked at it and thought how am I going to change this and he brought this guy in and already in the first four games we have been a lot better at it.
It is the small gains that can make big differences.
We are switched on when it comes to throw-ins - everyone is in better positions that we are finding easier, and the lads' techniques have got better.
We all got measured and I was one of the worst, but since the day he came in until now I think I've gained about six metres.
Gronnemark, who hold's the record for the longest throw in, has a protege in the Danish league in 25-year-old Mikkel Qvist. The Danish/Colombian midfielder plays or AC Horsens in the Danish Superliga, with the club making great use of his incredible range from throw ins:
An impressive highlight reel.
Gronnemark revealed in an interview with the Sun how he improved the length of Qvist's throw-ins:
I had a guy I coached called Mikkel Qvist from AC Horsens.
When I began with him, he could throw around 38 yards. Now, after I worked with him, he's getting almost 44 yards. He has an insane throw-in.
Of course we all know that Gronnemark likely developed his technique studying the the O.G. of long throw ins:
