Interestingly, Valencia wasn't the only United player dropping clangers on social media after the match at Old Trafford, with Paul Pogba also attempting a defiant statement of intent but missing out a crucial comma in the process...
A clip of Pogba and Mourinho having a tense exchange on the training ground emerged last week, and the Portuguese has told the 25-year-old France global he will not captain the team again. I'm talking about players in general.
The Sun is reporting that Mourinho has "lost the dressing room" and suggests that patience among the club's hierarchy with the manager is "waning".
"I think it's a bad situation".
Paul Scholes, the former United midfielder, said he was surprised that Mourinho survived after Saturday's defeat by West Ham United and the pressure on Ed Woodward, the club's executive vice-chairman, to sack him will heighten if the team fail to beat Newcastle United at home on Saturday.More news: Polls close, low turnout as Macedonians vote on new name
The 33-year-old "liked" an Instagram post from a fan account which said that "recently Mourinho has made watching us a punishment" and "it's time for Mourinho to go".
"I don't care what fallout you've had with your manager, I don't care if you've been at each other's throats, because that is part of the industry - people do fall out, it happens in other industries", Keane told Notts TV.
Valencia qualified for this year's elite European competition after finishing fourth in La Liga last season, but their start to the current campaign has been less positive. "Freedom of speech, free country, you can say what you want".
"You lose the game 3-1 and it's evident to everybody in that stadium or anyone around the world that watched that game that the attitude of the players and the intensity that they played, was wrong".
"Hopefully play with a bit of skill". On your bad days you roll your sleeves up and you fight for that jersey.
"And if you're a footballer for United, you put that jersey on, you walk out and you don't give 100 percent because you might be upset with somebody then good luck to Mourinho".
