"We need a break," Pulis told reporters in Thursday's press conference. "Having watched the Arsenal game against Swansea, the ref blows up 30 seconds before time is out. In our game against Newcastle, he plays three minutes over time in both halves. You need things to go for you and things haven't gone for us.
"The most important thing is you don't get too carried away or to despondent. That is what I would mark referees down on. You will make mistakes but big mistakes, mistakes that should not happen, are decisions that annoy people."
Palace, who are three points above the relegation zone in the Premier League table, will welcome Chelsea to Selhurst Park on Saturday.
