PFA chief executive Gordon Taylor admits he cannot defend QPR midfielder Joey Barton and the 'red mist' that descends over him.
Barton was handed a 12-game ban on Wednesday for his actions during QPR's dramatic 3-2 defeat to Manchester City on the final day of the Premier League season.
Barton was sent off for elbowing Carlos Tevez but then launched further attacks on Sergio Aguero and Vincent Kompany before being led from the field.
The 29-year-old later argued he had been trying to invoke retaliation from a City player in the hope that they too would be red carded.
That is a sentiment union leader Taylor finds hard to accept despite Barton being one of his members.
"It's very hard for us," Taylor told Sky Sports News. "You can't defend those actions.
"This was a game going out all over the world. A big game for Manchester City.
"He just did himself no favours by talking about taking one or two Manchester City players off with him.
"So it was quite depressing really and I have to say the game is bigger than all of us.
"The image of the game is important and it can't revolve around a single person.
"I'm not surprised at the sanction and fearful of course that we've now got to see the situation at Queens Park Rangers.
"But he's one of our members.
"He chooses what advice to take but it is a big worry because he's at a time of his life now where I felt things were going better - albeit at times with controversies about his social media.
"We'd actually spoken at conferences about that. When he's on track he's sound and articulate and good humoured.
"But there's a red mist that comes on him and from that point of view it just knocks you back to square one."
