Manchester United players “got away with murder” and behaved “shamefully” towards sacked manager Jose Mourinho, says ex-Red Devils captain Roy Keane.
Keane said it was indicative of the behaviour of modern players, whom he says are “very weak human beings”.
Mourinho was sacked on Tuesday, with former striker Ole Gunnar Solskjaer appointed caretaker manager until the end of the season.
You would fall out with these players,” Keane told BBC Radio 5 live.
“Players who turn up overweight, do not train properly and are not producing… for some to down tools, shame on some of those players.
“I am not Mourinho’s biggest fan, but I can’t tolerate footballers who hide behind agents, their pals in the media – it is a bit of a joke.”
Mourinho was sacked after two and a half years in charge, with United 19 points behind Premier League leaders Liverpool.
He was reported to have repeatedly fallen out with players, including record £89m signing Paul Pogba.
Former Republic of Ireland midfielder Keane, speaking to Adrian Chiles, added: “The players got away with murder. They hide behind the manager. They have thrown him under the bus.”
Keane spent 13 seasons at Old Trafford, winning seven Premier League titles, four FA Cups and the Champions League.
The 47-year-old said: “I was a bit old-school. But I would call it not old-school, but good-school.
“Whatever has gone on at the club, when you go on the pitch – particularly at a big club like United – you go out and give your all, no excuses.
“This idea that these players are upset… it is not just United, but the modern player. They are not just weak players, but are very weak human beings. You cannot say a word to them.
“Players are quick to hide behind social media, their cars and their girlfriend’s dog, the whole lot.
“I was very lucky with the dressing room I was in. There were good men, good leaders and characters, but that is in shortage in the game now.
“It would not have happened in our dressing room. We would not have tolerated lads not putting a shift in.”
