Manchester United's next Premier League match is at champions Manchester City on Sunday, Nov. 11.
"The written reasons for that decision were published on Wednesday and the FA has chose to challenge the ruling, meaning Mourinho could still face punishment".
Xavier was said to have contradicted himself and failed to provide adequate context in which Mourinho's remarks were made, which was considered essential to establishing if the manager was guilty of the charge. "His words were inaudible", the Commission explains, going on to add: "we accept Mr Valente's evidence that a typical person fluent in Portuguese colloquialisms would not feel insulted or offended from what they saw or interpreted from the footage, rather would understand JM to be very happy about something good that had just happened to him against all odds".
But on October 31 it was announced the FA charge against Mourinho of using abusive language had been "not proven".More news: Tesla names Robyn Denholm as new chairwoman to replace Elon Musk

Mourinho used Simao Valente, an assistant professor at the University of Lisbon and expert in the Portuguese language. He also argued that his words were "entirely inaudible, were directed to no-one, were comprehensible only to a person possessed of sufficient lip reading skills and a deep expertise in Portuguese colloquialisms".
Valente said that "the victory was vindication" and he did not consider the words used in the context to be abusive, insulting or improper.
The 55-year-old Mourinho said after the match he had been the subject of a media "manhunt".
It led the commission to rule: "We find that JM (Jose Mourinho) was celebrating victory without aiming the words at anyone in particular".
The FA brought in lip readers and linguistics experts to build a case against Mourinho, who in turn enlisted his own language experts to fight the charge.
