Liverpool have appointed the world-record holder for the longest throw-in as a part-time coach on Jurgen Klopp's backroom staff.
Thomas Gronnemark, who considers himself a professional throw-in coach and threw a football 51.33 metres in June 2010, has been hired by the club to improve their threat in dead-ball situations.
Gronnemark, 42, from Denmark, first worked with Liverpool players during a preseason training camp as Klopp hoped to strengthen his side's ability to retain possession after throw-ins.
Although Gronnemark is known for his long throws, he also advises players on how to use the restart to trigger their side's attack and how to avoid putting teammates in a position where they can lose possession.
