Everton manager Roberto Martinez accused Chelsea's players of "trying to influence the referee" and urged the game's authorities to examine what he views as their intimidatory tactics.
Martinez was left frustrated after seeing Gareth Barry shown a second yellow card before Willian scored a late goal to give Chelsea a 1-0 victory.
"It is very clear what the home team are trying to do is influence the referee," he said after the match. "Every time there is a challenge, it feels as if the weight of the world is on the referee's shoulders and he has to act.
"My players react to that and it is something unfortunate. It is something that constantly we see here [at Stamford Bridge] and it is something we have to let the authorities look in to.
"The reaction surrounding the referee and the [Chelsea] players' conduct, you don't want to feel it affected the referee's decision, but it is disappointing. That [red card] created belief for the home side and their goal comes from that.
"To give Gareth Barry a second yellow card because of the reaction of the Chelsea players is disappointing. It was just a flick, just a free kick. If you don't get that momentum, they don't end up in the back of the net."
Martinez also criticised Branislav Ivanovic's late clash with Everton midfielder James McCarthy, after the Chelsea player faced accusations he tried to head-butt his opponent.
Jose Mourinho -- who was again bemoaning Football Association inconsistency earlier this week -- had threatened to walk out of his postmatch news conference after being asked about the incident, but Martinez said: "If you look at the images, Ivanovic's behaviour is wrong.
"That shouldn't be allowed. He grabs James McCarthy around his neck in a very forceful manner, then he puts his head against him when James McCarthy never reacted one single bit.
"If you want to be on top of the laws, that's a red card. We got nothing out of that moment."
Everton had also lost 1-0 on their visit to Chelsea last season after a late goal, but Martinez felt his side's performance on Wednesday was more impressive.
"We were better in control this season compared to last," he said. "We had the best chances of the game and they needed two world-class saves from Petr Cech, and both were in key moments. It is unfortunate that we could not convert those chances.
"Overall the performance was exactly what we wanted. It was a huge disappointment that we couldn't reflect the performance in the scoreline. The performance did not reflect the result.
"It's a very unfortunate goal to give away. It goes through the legs of a player and it ends up in the back of the net. It was one of those games where football shows it can be very cruel."
