TOTTENHAM captain Son Heung-min had to intervene as James Maddison and Pedro Porro squabbled over free-kick duty.
Spurs were 1-0 against AZ Alkmaar just before the break when the set-piece was awarded.
Maddison picked up the ball ready to take it but was challenged by Porro - who tried to grab it from him.
The two were then in a heated exchange of words before skipper Son get between the two for Maddison to take the free-kick.
One fan said: "This is so embarrassing."
Another fumed: "I hate this nonsense with a passion."
One said: "Son Heung-min, a footballer with zero haters."
Another joked: "Why do they have to keep embarrassing me."
Maddison actually doubled Spurs' lead on 48 minutes and was joined in celebration by Porro.
His goal was sandwiched by two Wilson Odobert strikes which saw Tottenham win 3-1 on the night.

That was enough to see them progress 3-2 on aggregate, relieving the pressure on manager Ange Postecoglu.
Spurs play Frankfurt in the quarter-finals and Maddison said: "The next stage is what we set out to do at the start of the two legs.
"There was a lot of talk after last week's performance, we were honest with ourselves it wasn't good enough.
"I know what we're capable of here and we got the job done. We haven't achieved anything yet, we're in the quarter-final and we kick on and we look forward to it."
