The FA have charged Cesc Fabregas with two counts of misconduct after the allegations by Hull City coach Brian Horton were heard. Phil Brown was also charged but with only one count.
An FA statement said, "Fabregas faces two charges of improper conduct relating to his conduct on the pitch following the game."
One charge concerns his behaviour when coming on to the pitch after the final whistle. The second charge relates to an alleged spitting incident. The charges are based on submissions from Hull City and video evidence.
"It was nothing," Arsene Wenger is reported to have said when asked about the incident, which indicates that the Arsenal boss was aware of the truth behind Fabregas' spitting allegation.
The FA went on to say, "Brown is charged with improper conduct and/or bringing the game into disrepute in relation to media comments made after the game concerning referee Mike Riley."
Both have until the 12th of May to respond.
The Arsenal supremo, Arsene Wenger said, "I don't know if we will appeal—I will see what we can do about that."
