Pardew thought Guardiola's comments at the weekend about a lack of protection for his players primed the crowd to overreact, and also pointed to an alleged stamp by Fernandinho on Gregorz Krychowiak that went unpunished and led to the Poland international going off shortly afterwards.
"I thought Pep's comments at the weekend affected the crowd," said the West Brom boss.
"Every challenge they were saying, 'you're not protecting our players, referee'. There were a few songs sung about him, but I actually thought he had a decent game. His calls were correct and it was a yellow card for Phillips not doubt.
"He's a winger and in desperate situations wingers can make poor challenges. It was a poor challenge, make no mistake about that.
"I think Fernandinho made a similar one in the middle of the pitch. I'm not sure if the referee saw it. Gregorz struggled after that but I haven't seen it. He didn't think it was particularly great."
