Liverpool manager Jurgen Klopp raised eyebrows back in August with the appointment of Thomas Gronnemark.The Reds became the first Premier League club to hire a specialist throw-in coach - a decision that was met with much derision from critics.“I'm sorry, a throw-in coach? Here's the ball, pick it up with both hands, take it behind your head and throw it with both feet on the ground,” former Sky Sports pundit Andy Gray said following the announcement. “I'll tell you what, I'm officially a throw in coach and I'm also going to some clubs later this month to teach them how to kick off. I want to be the first kick-off coach.”However, there was clearly some logic behind Klopp’s decision. The Liverpool boss was impressed after meeting the 42-year-old Dane, who holds the world record for the longest throw-in at 51.33m, and knew straight away that he wanted to employ him."To be honest, I'd never heard about a throw-in coach," Klopp told reporters. "When I heard about Thomas, it was clear to me I wanted to meet him; when I met him, it was 100% per cent clear I wanted to employ him.""I know it is totally the weirdest job in the world," Gronnemark, who thinks he is the world's first throw-in specialist, told BBC Sport."In general against Liverpool I would not want to put the ball out for a throw-in. I am not saying Liverpool will do a lot of long throw-ins, but you never know when they may do it."

Gronnemark, who Klopp felt had made an instant impact with his work at Melwood, picked out Joe Gomez as one of the Liverpool players who was looking dangerous following his coaching.

"If I was a defender I would not want to be on the end of one of Gomez's throw-ins," he added.

Fast-forward two months and Gomez’s new long-throw technique played a part in England booking their place at next summer’s UEFA Nations League finals in Portugal.

In desperate need of two goals against Croatia with 12 minutes remaining, Gomez launched the ball into the box. It eventually found its way to Jesse Lingard, who netted the all-important equaliser at Wembley.

Gronnemark couldn’t resist tweeting after seeing his coaching benefit England at Wembley.

The Dane tweeted: “Very proud of Joe's throw-in 💪⚽👍🔴 #liverpoolfc #throwincoach #LFC #ENGCRO“

He was then praised by many football fans in the replies…

Gronnemark also mentioned that Trent Alexander-Arnold and Andy Robertson’s throw-ins have both improved following the specialist coaching.

However, he can’t see anyone at Anfield breaking his world-record just yet…
