Manchester United midfielder Marouane Fellaini has urged referee Lee Probert to take action against Fulham defender Sascha Riether, after the right-back appeared to stamp on youngster Adnan Januzaj in Saturday's Premier League clash between the two sides.
Fellaini was one of the closest players to the incident and was immediately furious with Riether over the challenge.
He later told MUTV, per Sky Sports: "For me it was a red card for the right-back. I hope the referee looks at the video later."
The incident ended up being one of the major talking points of what was otherwise a fairly uneventful win for United. Tempers flared as a result of the challenge.
Januzaj was quick to jump up and remonstrate with the German, who had stood on his ankle, but referee Probert took no action at the time—for which no explanation has been given.
Dangerous challenges were a talking point of the weekend in general, with Sunderland's Andrea Dossena seeing red for a nasty stamp on the shin of Hull's David Meyler.
Mirror Football's Mark Lawrenson, a former Liverpool defender turned Match of the Day pundit, has also called for Riether to be banned by the FA for his actions. He also suggests that Meyler should take legal action over the nature of Dossena's challenge.
Neither challenge was a legitimate attempt for the ball and, thus, should be dealt with harshly by the game's authorities:
Januzaj, though, will have to become accustomed to aggression from defenders.
The likes of Neymar are accused of diving but are on the receiving end of semi-regular violence from defenders who struggle to get near him in regular circumstances.
It is one of the perils that the game's most talented players must face, and in this instance, Januzaj was on the receiving end of one of the nastier challenges he will be confronted with this season.
