Everton manager Roberto Martinez accused Chelsea's players of trying to sway the referee during a bad-tempered 1-0 defeat at Stamford Bridge.
Willian's late winner came after Gareth Barry's red card and a fracas in which Branislav Ivanovic escaped censure for a clash with Everton's James McCarthy.
"It's very clear that what the home team are trying to do is influence the referee," Martinez told BBC Sport.
Mourinho cut short his BBC interview when asked about Chelsea's discipline.
A game that looked destined for stalemate came to life in the closing stages after Barry was shown a second yellow card for a trip on Willian.
As opposing players clashed, Ivanovic locked his arm around McCarthy's neck and appeared to push his head towards the Everton midfielder.
Martinez criticised referee Jonathan Moss for his handling of both incidents.
"To give Barry a second yellow just because of the reaction of the Chelsea players, that is disappointing," he said.
"You don't want to believe that that decision is given because of the reaction of the players. It's something that we constantly see here. We have to allow the authorities to look into it.
"Ivanovic's behaviour is wrong. He grabs McCarthy around his neck in a very forceful manner, then puts his head against him. James McCarthy doesn't react a single bit.
"If you want to be on top of the law, that's a red card and we got nothing out of that moment."
Mourinho has only recently returned from a self-imposed 10-day media silence after accusing the press of influencing the Football Association's decision to punish Chelsea striker Diego Costa for a stamp of Liverpool's Emre Can.
When pressed on the latest flashpoint in a post-match interview with BBC Sport's Jonathan Pearce, Mourinho decided to walk out, telling Pearce: "Sorry, see you tomorrow."
He later conducted a short interview with Pearce in which the subject was avoided, but reacted angrily once again when the Ivanovic incident was raised during a news conference with other media.
"I'm concerned with my reaction because one more question and I leave," he threatened. "And after that you are not happy. The next question for that story, I have to go."
Former Arsenal defender Martin Keown said he does not expect Ivanovic to be punished and suggested Mourinho enjoys the controversy.
"Ivanovic puts his arm around his throat and then the head goes towards him," Keown said on BBC Match of the Day.
"I think he is just about going to get away from this. I don't think there is quite enough of his head making any real contact.
"What it is with Mourinho is that he wants that injustice. For me, it is propaganda. If Ivanovic gets suspended, it just goes towards the cause.
Aston Villa have sacked manager Paul Lambert after dropping into the Premier League relegation zone.
Tuesday's 2-0 loss to fellow strugglers Hull City was the West Midlands club's 10th league game without a win.
They have also managed just 12 league goals from 25 games - the lowest in Premier League history.
First-team coach Scott Marshall and goalkeeping coach Andy Marshall have taken temporary charge with 13 league matches remaining.
Football pundit Pat Nevin said the sacking had been coming given Villa's precarious league position, the lack of goals and the lack of entertaining football for Villa fans at home.
"Paul's a friend of mine, but that one is an absolute stick on," Nevin told Radio 5 live. "It was going to happen."
Disgruntled Villa fans had called for the 45-year-old Lambert, who was appointed in 2012, to go during the game against Hull.
After the match, the Scot said he had been aware of the discontent "months ago" but was determined to battle on:, insisting "I've told the players they've got 13 cup finals."
Only two weeks ago, Villa chief executive Tom Fox had told BBC Sport said Lambert would remain in charge, adding that to sack him would be like "flipping a coin".
Fox added: "When things aren't going well, fans bay for that type of blood. That's not the way that I or the owner are going to make a decision. It's a false narrative."
Villa's decision to sack Lambert came just hours after the Birmingham Mail started a campaign to oust the former Norwich boss.
Their front and back pages were covered with the message: "Birmingham Mail says: Lambert Must Go!"
It was accompanied by the hashtag #lambertout.
Birmingham Mail editor Marc Reeves told BBC Midlands Today that his newspaper wanted to give "hundreds and thousands" of Villa fans the opportunity to have their say on Lambert.
"It's a voice that needs to be listened to and the Mail wanted to play its part in amplifying that voice to the Aston Villa board," he said.
Liverpool assistant manager Colin Pascoe believes Mario Balotelli fully deserved his first Premier League goal, which sealed a crucial victory over top-four rivals Tottenham on Tuesday night.
In a frenetic clash at Anfield, the sides were locked at 2-2 before the maverick Italian came off the bench to net the winner with seven minutes remaining.
Balotelli has struggled since arriving on Merseyside from AC Milan in the summer, and had been left out of the previous three squads by manager Brendan Rodgers.
But Pascoe said his goal was a reward for his hard work during his spell away from the first-team.
"Mario always works hard in training and recently he has been ill and he has had some knocks on his foot where he couldn't get his boot on," said the Welshman, standing in for Rodgers who had left to board a flight to watch a match in Europe on Wednesday.
"It is testament to himself, he kept going and got his reward."
Considering he had waited all season for the goal, the striker did not look particularly pleased with his effort.
In true Balotelli style, there was no celebration and straight after the final whistle he headed off down the tunnel without shaking hands with team-mates or opponents, or acknowledging the fans who still back him despite his disappointing campaign.
But Pascoe insisted: "He is immensely happy.
“To get a winner at Anfield, I am sure he is happy. Again, with Mario he knew he would have a part to play and he certainly did.”
The victory was vital to Liverpool's Champions League ambitions as it moved them within three points of third-placed Southampton, who have a match in hand, and Arsenal in fourth.
"We needed to win tonight to get closer to the top," added Pascoe.
"We always thought that. Our next [league] game is Southampton and we will look at that to get three points and keep closing the gap." See Balotelli's goal
Egypt's public prosecutor orders inquiry after 40 killed and dozens hurt in chaos at football stadium in capital.
Egypt has suspended its football league and ordered an investigation after at least 40 people were killed and dozens injured in a stampede and clashes between police and supporters of Zamalek football club at a game in Cairo, officials said.
According to witness accounts, violence erupted when police tried to set up barricades and used tear gas to disperse football fans trying to force their way into the army-owned stadium in the city's northeast on Sunday.
Egypt's public prosecutor ordered that an investigation begin immediately, while the incident prompted the government to postpone the Egyptian Premier League indefinitely, the prime minister's office said in a statement.
The Egyptian Interior Ministry said the clashes occurred after supporters of Zamalek, known as Ultras White Knights, tried to attend the game without buying tickets.
"Huge numbers of Zamalek club fans came to Air Defence Stadium to attend the match ... and tried to storm the stadium gates by force, which prompted the troops to prevent them from continuing the assault," the ministry said.
The fans posted on their group's official Facebook page that the violence began because authorities only opened one narrow, barbed-wire door to let them in. They said that sparked pushing and shoving that later saw police officers fire tear gas and birdshot.
"Suddenly they closed the gate and told us to get out through another gate," a witness told Al Jazeera.
"The police were in front and behind the gate. They fired tear gas. This caused panic and people fell on top of each other. We started to leave quickly. There were old people in the crowd and they were crushed by other fans."
Raheem Sterling will NOT sign the new Liverpool contract being offered to him, talkSPORT understands.
Reds chief Brendan Rodgers has described the deal as 'incredible', and claims the club will not be held to ransom by the 20-year-old's representatives.
The Anfield flyer has had the deal on the table for more than a month, but has yet to agree terms with the Anfield club.
Sterling has two years left on his current contract, and has attracted the attentions of European giants Real Madrid.
The Spaniards are ready to make a bid in the summer if a new contract cannot be agreed.
