Unhappy Stoke City boss Mark Hughes blasted referee Mike Dean for costing his side in the defeat to Sunderland.
The visitors were reduced to 10-men two minutes after the re-start when Ryan Shawcross was shown a second yellow card after a foul on Duncan Watmore, the young forward terrorising the Stoke defence.
Replays showed Shawcross - who'd been booked just before the break for a foul on Steven Fletcher - appeared to get to the ball first.
And fuming Hughes believes Dean should have shown more "common sense" before flashing a red.
"The sending off was a key moment," reflected Hughes.
"Just a couple of minutes into the second half, it had a detrimental affect on our ability to win the game.
"I thought the referee should have shown common sense, to be honest.
"Ryan felt he got a touch on the ball and if that is the case then he got their first.
"The referee should have given him the benefit of the doubt.
"He didn't and made the decision, with the help of the assistant on that side and then we are down to 10-men."
Black Cats boss Sam Allardyce, who felt Dean got Shawcross' dismissal correct, looked to take advantage of having the extra man, with Jeremain Lens and Adam Johnson unleashed as second-half substitutes.
It took Sunderland until the 82nd minute to break down a stubborn Stoke defence though, Patrick van Aanholt scoring from a disguised free-kick routine.
Johnson, fouled for the free-kick, rolled the ball to the Dutch defender who smashed the ball home from 20-yards past in-form England stopper Jack Butland.
Hughes accused Johnson of going to ground too easily in winning the free-kick, and he was less than impressed that Dean decided to give it.
"Even with one less man, Sunderland didn't cause us too many problems," added Hughes.
"They needed the break and they got it because the referee got the decision for the free-kick totally wrong.
"Their lad Johnson has dived, jumped out of a non-tackle.
"To add further punishment to them scoring from the goal he then saw fit to book Erik Pieters too.
"It takes some strike to beat Jack from 20-odd yards, so give [Patrick van Aanholt] credit for winning the game.
"The second is an irrelevance, we were pushing for an equaliser and got caught on the break.
"Overall, we have played better in recent weeks.
"We were very much in the game but key moments went against us."
