Wigan boss Roberto Martinez was clearly unhappy with two non-decisions by referee Alan Wiley in the 3-0 loss to Tottenham on Sunday.
The Spanish tactician was of belief that Spurs striker Jermain Defoe should have seen red for a challenge on Gary Caldwell and thought Tom Huddlestone also should have been sent off - two decisions that would have completely changed the dynamic of the match.
"We knew the first goal was going to be paramount today. It should have been disallowed," Martinez said.
"It is hard to explain. He is one and half yards offside and the linesman has no one in his vision. A goal then changes the game.
"Defoe and Huddlestone did enough to be sent off. The challenges are very straightforward. Defoe has both feet off the ground and it is clearly a red card.
"Huddlestone has already been booked for one challenge and the next one is also worthy of another yellow.
"I do not like to be critical of the referee but it is hard to explain his performance today."
