Roberto Martinez accused Barclays Premier League officials of persecuting Wigan in their fight to stay in the Barclays Premier League after two more decisions cost his side dearly in their 2-1 defeat at Chelsea.
Latics boss Martinez insisted both Blues goals should have been ruled out for offside after watching Juan Mata's 93rd-minute winner deny his side a result that would have lifted them out of the bottom three for the first time in almost four months.
Martinez said: "Unfortunately, we have had too many times this season when it's not about matter of opinions, it's about clear calls that have been against us. I don't want to go into the debate that it's very easy to referee against little Wigan but, unfortunately, I believe this is the best league in the world and we should get better decisions than that."
Martinez's men were heading for a well-deserved 1-1 draw when substitute Mohamed's Diame's 82nd-minute equaliser cancelled out Branislav Ivanovic's opener, which was scored from a blatantly offside position.
That saw Wigan's players surround referee Mike Jones and assistant Dave Bryan, but to no avail. Martinez, who absolved Jones of blame, said: "If I speak with them, it will be a waste of time."
Citing previous decisions against Manchester United and Blackburn, Martinez added: "The sending-off at Old Trafford that was rescinded, that was an incredible decision. The corner-kick that was never taken against Blackburn. And, last year, we came here and Fernando Torres impeded Ali Al Habsi and it was a goal. It's happened too many times."
Speaking later to BBC Sport, a "furious" Martinez was even more outspoken, claiming Wigan were "robbed" by a "disgusting" and "horrific" performance from the assistant referee who made "shocking" decisions.
Meanwhile, Chelsea caretaker boss Roberto Di Matteo claimed he had yet to see a replay of either of his side's goals.
He said: "But, despite all that, I think that Wigan were really unlucky not to get something out of this game. Because they played very well, they put a great performance in."
Di Matteo admitted the Blues suffered a hangover from Wednesday night's Champions League win over Benfica, despite making seven changes. He said: "After you play a midweek game in the Champions League, there's always a concern that you might have a little hangover for the weekend game."
