The Football Association on Tuesday wrote to Hughes, who stated that the referee’s performance was “mystifying” and “laughable,” asking him to explain his comments that Clattenburg had “passed judgment on Bellamy” to a member of Manchester City’s backroom staff as they walked to the field after the half-time interval.
City will ask Bolton or Sky for any available footage over the alleged conversation.
“I don’t appreciate it when referees go out for the second half telling my support staff who they like and do not like in my team,” Hughes said after the game.
