Tony Pulis has admitted that he is "disappointed" by a lack of consistency from match officials in Stoke City's recent matches.
Last weekend the manager was angered by the decision to send off City defender Robert Huth.
Following the conclusion of today's 2-1 loss at Fulham, Pulis felt that Whites striker Pavel Pogrebnyak should have seen red for a challenge on Wilson Palacios.
"Last week we had Robert Huth sent off for a challenge where he is going in and has pulled his two feet away and had both feet facing the ground," Pulis told reporters. "We have seen a challenge today from the Russian lad on Palacios where he catches Wilson on the knee. The referee didn't see it.
"Kevin Friend, the fourth official, is stood where we are and it was a very poor challenge.
"The kid doesn't even get a yellow card. The inconsistency in respect of incidents this season is really, really poor."
Stoke are 13th in the Premier League table following today's defeat.
