Wayne Rooney is used to getting abuse during big away games.
When the former Manchester United striker plays Liverpool at Anfield or Manchester City at The Etihad, he knows full well that the home fans are going to give him non-stop grief.
Being the all-time record goalscorer for the Red Devils means that stick from supporters of United's rivals comes with the territory.
Similarly, being one of the finest strikers the Premier League has ever seen means Rooney is accustomed to opposition fans doing whatever they can to put him off his game.
Even so, when the 31 year-old trotted out with his Everton team mates to play Brighton at the Amex, he probably wasn't expecting a particularly hostile reception.
After all, why would he?
Everton and Brighton have no great rivalry or history. This was Rooney's first Premier League clash against the Seagulls. He has no links to Crystal Palace, Brighton's fiercest rivals.
And yet - despite the fact England's record goalscorer has never said or done anything to harm Brighton - a large section of the home supporters booed him relentlessly, jeering his every touch during the 1-1 draw.
Somewhat understandably, football fans everywhere were a little mystified…
Of course, Rooney being Rooney, he responded to the abuse in trademark style…
…by tucking away the late penalty that secured his side a 1-1 draw.
Under-pressure Everton boss Koeman was heading for a fifth defeat in six league games until the late drama salvaged a point.
Brighton captain Bruno elbowed Everton forward Dominic Calvert-Lewin and referee Michael Oliver pointed straight to the spot.
Rooney slotted home and Everton’s travelling fans celebrated wildly as they managed to nick a result to change the mood with Koeman’s position becoming under increasing threat.
That frustrated Brighton who had taken an 83rd minute lead through Anthony Knockaert and the home fans thought they were on the way to a third consecutive home win.
It was tough on Brighton but neither side really did enough to win the game and a draw was just about a fair result.
Brighton keeper Mat Ryan then made a dramatic last gasp double save to stop Everton nicking the win in injury time.
Brighton’s fans jeered Oliver off the pitch after the penalty award but replays suggested Bruno led with his elbow.
