Mark Clattenburg has resigned from his role as a refereeing consultant with Nottingham Forest, saying his presence had become a "hindrance" to the club.

Retired Premier League referee Clattenburg – who oversaw the 2016 Champions League final and the showpiece game at Euro 2016 – began the role in February.

The appointment was roundly criticised but Forest – who have seen a number of debatable decisions go against them this season – said it would aid their understanding of the decision-making process and improve dialogue with refereeing body Professional Game Match Officials Limited (PGMOL).

However, Clattenburg has continued to attract criticism for taking on the role, which intensified when Forest reacted to a 2-0 Premier League defeat at Everton by accusing Stuart Attwell – who was on VAR duty – of being a fan of relegation rivals Luton Town.

That came after Forest had seen three penalty appeals knocked back at Goodison Park, and Clattenburg avoided condemning Forest's statement in the aftermath of the controversy.

On Friday, Forest released a statement from Clattenburg, who defended his decision to take the job but acknowledged it had created unforeseen difficulties.

Clattenburg said: "It is now clear that the existence and performance of these consultancy services has caused unintended friction between Nottingham Forest and other participants, to the extent that it has become more of a hindrance than help.

"It has also led to the unmerited targeting of me, personally, by certain participants and pundits.

"Such reactions and outcomes were not expected and are regrettable, as it is my sincere belief that there is a place for and value in such a role in the modern game."
