Pulis claims Mamady Sidibe’s disallowed goal in the first half of the game was an ‘injustice’.
John Carew secured a 1-0 win for Aston Villa.
“It’s an injustice, it’s a disappointing decision,” Pulis told Sky Sports. “But we’ve had quite a few things go against us since we’ve come into the Premiership.
“But we’ll just take it on the chin and get on with it, you have to, and hopefully next week we might get a decision for us you never know.
“We’ve played well today. Obviously the decision is a poor decision but we’ve played well today and we can take a lot out of the way we played and especially the chances we created.
“They’re a good side Villa. Martin’s (O’Neill) done a fantastic job here and they are going to be there or thereabouts.
“But we’re desperately disappointed because they’ve had a tough week. When you think, nine points they’ve picked up in three games, Martin will be absolutely delighted – away trips to Manchester United and Sunderland and then coming back home on the third game is not easy.
“So you have to give them a lot of credit.”
“I actually think we’re playing better now than what we played last year,” he added. “We just need a few results to be honest to give us the confidence to push on.
“But our performances, especially away from home, have been very, very good this year.
“There’s been one or two occasions where we’ve let ourselves down but generally we’ve played better as a team.
“We need to score goals, that’s the big problem for us at the moment.
“If you look at the goals return we’ve had from the forwards that we’ve got, we’ve got to do better.
“Everybody’s in it together, we’ve got to defend better, we certainly created more chances.
“We look a lot more fluid when we go forward but we have got to start taking the chances that are coming along.”
