Tottenham Hotspur supporters who booed goalkeeper Guglielmo Vicario were told afterwards "they can't be true Tottenham fans" by boss Thomas Frank.
Spurs conceded twice in the opening six minutes to lose 2-1 to Fulham, their 10th Premier League home defeat of 2025.
But the main talking point was Fulham's second goal when Vicario lost possession well outside of his box.
He came out to deal with a long ball and took the ball towards the touchline.
However, instead of booting it out of play, the Italian turned and tried to clear, but slipped as the ball skimmed off Harry Wilson and was controlled by Josh King
King laid the ball off to Wales midfielder WIlson, who curled a shot into the goal from the touchline measured at 36.6 metres.
Moments later when the ball came to Vicario again, some Spurs fans booed him.
Despite Vicario's mistake, it was not an easy goal for Wilson to score.
In fact it was the second longest-range Premier League goal of the season â after Tyler Adams' 43.3m goal for Bournemouth against Sunderland, which incidentally also came on Saturday.
Wilson said he was a "little bit surprised" that he still had an empty goal to aim for.
Ten seconds passed between Vicario coming out of his box and Wilson shooting - which was five seconds after the clearance.
"I felt like the goalkeeper was out of the box for ages," Wilson said.
"I was surprised none of the back four went back to the line. When none of them defended the goal, my eyes lit up a bit.
"[Destiny] Udogie slipped too, which gave me a bit of extra time. Then it was all about trying to make the right contact and get it on target. I had a good feeling, as soon as it left my foot, that it was on the right line."
