When Romelu Lukaku slotted the ball into the Everton net the Manchester United striker had no intention of holding back on the celebrations.
Especially after being jeered during Sunday's Premier League game by the Everton fans who revered him before an offseason transfer across northern England.
The Belgian, who cost STG75 million pounds ($A127 million) cupped his right ear to those supporters.
"The celebration was just a bit of banter," Lukaku said after scoring the third goal in a 4-0 drubbing of Everton. "I missed the free kick and they jeered me but I scored the rebound."
It compounded the miserable run for his former club. It's now four consecutive losses in all competitions, three in the league, with Everton conceding 12 goals without reply in the process.
So early in the season, it's looking bleak for Ronald Koeman's side who demonstrated such ambition in the summer when they spent STG140 million pounds ($A238 million) on talent.
The poor run of form started with a 2-0 loss last month to Chelsea, who were held 0-0 by Arsenal in Sunday's other game.
Only alphabetical order separates Manchester United and neighbour City at the top of the standings. After five games they have identical records with four wins apiece and a draw each. Both have scored 16 times and only conceded twice.
Yet it was only Antonio Valencia's half-volley in the fourth minute separating United and Everton until the 83rd minute when Henrikh Mkhitaryan slotted in a second. Lukaku struck in the 89th minute and a handball by Morgan Schneiderlin allowed Anthony Martial to slot in a penalty in the second minute of stoppage time.
At the end of a week when fellow Dutchman Frank de Boer lost his job after only four games at Crystal Palace, Koeman is feeling the heat at Everton.
"We need to win, if you don't win then it is better to stop," Koeman said. "Every manager in life has doubts. There is nobody who doesn't have doubts as a manager. And if you don't win you know you have a big number of players in your squad, and you have doubts about what system to play. This is normal. Of course I ask myself the question 'Why?' Why?"
For the fifth time in eight matches, Chelsea had a player sent off. But David Luiz's dismissal in the 87th minute for a high, sliding challenge on Sead Kolasinac came too late for Arsenal to produce a winner.
"There was a battle all over the pitch and we responded well in domains where we were questioned," Arsenal manager Arsene Wenger said.
"Overall, first it was important at least not to lose today and you could feel that in the team. In the last 20 minutes we played with that in our minds."
