Steve Cooper revealed he spoke to the Football Association about the appointment of referee Andy Woolmer before the 1-1 draw against Sheffield Wednesday which ended in controversy following a disallowed Swansea goal.
Kasey Palmer's last-gasp goal was ruled out amid Swansea claims for a penalty during an incredible goalmouth scramble in the Wednesday six-yard box.
Swansea boss Cooper was furious over the disallowed goal and was unhappy that Nothamptonshire official Woolmer had been appointed for the Liberty Stadium clash.
Woolmer refereed five Swansea matches last season and, although Cooper chose not to elaborate why he was upset by his appointment for the Owls' visit, he did reveal that he had spoken to the FA about the matter.
"It was a performance I predicted from the official and one that I spoke to the governing body about a few days ago," Cooper said after Andre Ayew's superb solo effort had cancelled out Adam Reach's first-half strike for Wednesday.
"My prediction was right. One thing was for sure, that, whatever the decision was, it was not going to us. It's personal unfortunately.
"There were a few warning signs with the appointment, and maybe my gripe isn't just with the performance on the pitch. Maybe it's with how he came to be here.
"I don't want to say too much, because we know who loses in these situations, and it's me and the club with a fine.
"I thought I knew where things were going to go, and sometimes I don't get things right, but I did with this one."
Cooper also felt that Swansea midfielder Korey Smith was fortunate to escape serious injury following a second-half challenge from Owls substitute Liam Shaw.
Smith could clearly be heard telling the Wednesday bench that it was a "red card offence" and Cooper said: "He's got an awful gash on his calf.
"You can see why he's angry with certain people. If you look at the gash and see the feet was high, you can see why Korey was frustrated. It could have been a lot worse."
The draw gave Tony Pulis his first point as Wednesday manager two games into his Hillsborough reign.
"The lads have worked really hard, they're a really good group of lads," Pulis said.
"There are lots we have to work on and lots I'd like to put in place, but to think we had six players out.
"Those players would have started so they've done fantastically well, especially with two away games in a row.
"We won't get back until 2 o'clock in the morning whereas Stoke played at 7 o'clock last night, so they will have two days more rest than us. It's something the EFL should look at."
