Alan Pardew criticised referee Lee Mason for not sending off Francis Coquelin for what the Crystal Palace manager perceived to be persistent fouling in Arsenal's 2-1 win at Selhurst Park.
Coquelin was booked late in the first half of Sunday's Premier League clash and was perhaps fortunate not to get another yellow before the break, Mason giving the midfielder the benefit of the doubt following a foul on Wilfried Zaha.
Pardew was incensed by Mason's decision not to issue a second booking, a decision that could have seen a different result.
He said: "I said to Lee Mason 'Listen. That tackle before half-time is not a sending off at that point, but that's his last chance, you know that'.
"He then makes the foul and he's [should be] off at that point. Arsene Wenger knew that and substituted him straight away.
"It's a decision Lee Mason needs to be braver on."
The Frenchman added: "I felt it he was not fortunate. I would like to see that again, but in the end the pressure created by the crowd meant I took him off.
"When you are 2-1 up and he is playing quite well that's difficult. It's a sensitive decision."
