Robert Huth joked he had 'taught' Marouane Fellaini well after the Manchester United midfielder was pictured pulling the hair of Arsenal's Matteo Guendouzi.
The Arsenal youngster was racing clear and in a game that soon became dominated by the fouls, Fellaini clutched onto the Frenchman's hair to bring him down.
For Huth, the moment on Wednesday night evoked memories of his own tug on Fellaini's now obsolete afro hair.
The former Leicester City defender has previous with the gangly midfielder after picking up a three match ban for pulling on the Belgian's afro at Old Trafford in 2016.
That sparked a furious reaction from Fellaini as he elbowed Huth and both were reprimanded.
In an attempt to defend the actions of his midfielder, then United boss Louis van Gaal said: 'It's not in the books that someone has to grab by the hair and then pull it behind - only in sex masochism.'
The latest hair-pulling incident involving Fellaini came in for heavy criticism from Arsenal fans who want to see retrospective action taken.
Unlike the Huth incident, this foul was seen by referee Andre Mariner and the player was spoken to.
He was not booked and many Gunners supporters felt he had been let off lightly.
Twitter user NikonPhil was part of a growing consensus after the match, tweeting: 'Fellaini should be banned, no excuses for the way he plays.'
There was agreement from CMorgs1975, who added: 'He's a compete low life. This should be reviewed and Fellaini charged.'
One user, GRMDAILY, even likened the act as being similar to that of a punch or a bite.
