Everton manager David Moyes called on referees to give Marouane Fellaini more protection and voiced anger at Wigan's tactics during Saturday's 2-2 draw at the DW Stadium.
Fellaini was involved in a controversial first-half incident when he was booked by referee Kevin Friend for an alleged elbow on Maynor Figueroa.
Wigan boss Roberto Martinez initially said he felt the Belgian midfielder should have been sent off, but later changed his mind and said a yellow card was the correct decision.
But Moyes feels Fellaini gets a raw deal from officials, leading him to consider calling referees' chief Mike Riley to put across his case.
The Everton manager told the Liverpool Echo: "I think Fellaini needs more protection. He was two feet above Figueroa, and anyone who has played the game knows you need to use your arms to get elevation. The only thing that Figueroa could have headed was his arm and his hand, and it was his hand.
"I can't understand what, in their penalty box when we have a corner kick, Fellaini would be doing to the Wigan players? Why would he be trying to foul? He is just standing there and they are standing on his toes."
Moyes suggested that Wigan got several favourable decisions at the end of a week that saw Martinez fined £10,000 by the FA for suggesting his side were always unfairly treated by officials whenever they faced Manchester United at Old Trafford.
"I think Roberto Martinez has done a good job over the last few days of making sure that the referees gave them what was required," the Scot said.
"We found it really hard to play against Wigan, and then we also found it hard the way the decisions went."
Moyes was annoyed about Arouna Kone's opener for Wigan, which looked offside, and by the fact that Nikica Jelavic had a penalty appeal rejected. "The first goal is offside, definitely – half a yard offside," he said.
"And the linesman's nowhere in line with the ball because I've had a look. He's three or four yards behind the ball, not in line. Jelavic is a penalty kick, so I think we've had a really rough day with the decisions. What we got we earned ourselves."
Everton were awarded a late penalty when Figueroa fouled Kevin Mirallas, allowing Leighton Baines to equalise, and Moyes said: "The penalty we got was actually a double penalty kick because it's a foul on Victor Anichebe and it's also one on Kevin Mirallas.
"Yes, we can approach Mike Riley and I am sure others do, but Mike Riley has to look at the people who are working for him and whether they are doing well enough."
