Manchester United and Manchester City have avoided punishment by the Football Association following the alleged tunnel bust-up in the wake of the Premier League clash at Old Trafford earlier this month, while Jose Mourinho will not face any disciplinary action for his comments before the game.
Having studied the written submissions provided by both clubs after the Dec. 10 game, which City won 2-1, the FA has confirmed that no action will be taken against United or City.
"Following a review of the evidence provided by the clubs and independent eyewitnesses The FA will be taking no formal action," an FA statement read.
With Greater Manchester Police also choosing not to take the matter further, it now appears that the authorities regard the incident as closed.
But the ill-feeling between United and City is unlikely to be gauged fully until the two teams meet again in the Premier League at the Etihad Stadium on April 7 -- United's defeat against Bristol City in the Carabao Cup having denied Mourinho's team the opportunity to avenge the recent derby defeat with a two-legged semifinal against City next month.
The alleged tunnel bust-up centred around reports of Mourinho being hit by milk thrown from inside the City dressing-room after complaining about the volume of celebrations by Pep Guardiola's players.
Sources told ESPN FC that City coach Mikel Arteta suffered a cut to the eye in the melee, but the FA have judged that neither team crossed the line sufficiently to warrant a charge.
Mourinho, meanwhile, will not face any disciplinary action from the FA for his comments before the Manchester derby but has once more been warned about his future behaviour.
The FA did not specify which prematch remarks it was investigating but it is understood to have been concerned by the United manager's suggestion that City players make "tactical fouls" to break up opponent's attacks.
Mourinho was asked to explain himself last Thursday, with a deadline of this Monday for his observations.
In a statement, the FA said it has decided to take "no formal action'' after reviewing evidence provided by the club but has "reminded Jose Mourinho any further public comments about match officials may result in disciplinary action" -- the former Chelsea boss has previous in this regard.
