Report: PGMOL investigate referee Mark Clattenburg signing with agency

Professional Game Match Officials Limited has reportedly launched an investigation after Premier League referee Mark Clattenburg joined a management agency that also represents players.

Last week Catalyst4Soccer announced via the below tweet that Clattenburg, 40, was a new client.

According to PA, PGMOL had initially granted Clattenburg permission to join the group so that he could be helped with his off-field activities like after-dinner speaking and charity appearances.

However, PGMOL are said to not have been aware that Catalyst4Soccer also represents players and is now deciding if there is potential for a conflict of interest.

Manchester City goalkeeper Willy Caballero is one of the clients on Catalyst4Soccer's books.
