The Magpies boss initially sought clarification of the decision when the Argentine was given his marching orders for a challenge on striker Luis Suarez.
“I didn’t see it [the tackle] initially so I had no view. The fourth official was not exactly sure of why [he was sent off] and he said that to me and that confused me a little bit more,” admitted Pardew.
“Because it was my captain I wanted to speak to the referee and he told me it was for serious intent and foul play so I said OK.”
Pardew had the opportunity to look at television replays of the incident and has conceded that he can see the viewpoint of the official.
“When I had the referee’s version I wanted to see it and looking at it from one angle it looks very poor,” he stated.
The Magpies boss is confident that there was no malice in the tackle from his defender on the Liverpool striker.
“But I spoke to Colo [Coloccini] and there was no serious intent. I’ve looked at it from another angle and he stops himself going right through Suarez," added Pardew.
“I can understand why they have sent him off and I think it is a decision that we are going to accept. That is my gut feeling.”
Pardew also has a concern over defender James Perch who had to come off in the first half.
“Perch’s injury looks serious. He is the type that would play through but there was no chance of that and it doesn’t look too good,” said Pardew.
