Crawley manager Richie Barker was left to question referee Gavin Ward after his side lost 2-0 to Sheffield United on Saturday.
Tony McMahon curled home two free kicks at the Broadfield Stadium as the Blades went top of League One, but Crawley were unhappy with the decisions which led to the goals.
Referee Gavin Ward dismissed Hope Akpan in the previous Crawley match he officiated, and Barker was left to question the big calls again after Joe Walsh was penalised for a foul for McMahon’s opening goal.
Barker said: “The players are an honest bunch and from their reaction they were pretty clear. I need to speak to the referee’s people at the top and find out why he keeps getting our games and making mistakes that cost us. These decisions are too important to be guessing, and if that’s a guess it has cost us.”
The Reds enjoyed long spells of possession, but were unable to seriously trouble Blades keeper George Long. But Barker said his side could take pride from their performance.
“We got beat by two very good free kicks,” he declared. “It’s not as if they carved us open, there was no disgrace at all.
“I think the players should take immense pride, they were excellent and have taken the team who will probably win the league down to two free kicks. On another day we might have come away with 0-0. (Sheffield United manager) Danny Wilson has got players who can do that and can make a difference.”
