You'd think even a boy would know that when you go to see Liverpool play, the last thing you should wear is the shirt of Manchester United, their hated arch-rivals.
And this young lad felt the full force of Liverpool fandom when a stadium full of Kop supporters chanted and jeered at him, eventually managing to strip off his controversial kit.
He tried to remain inconspicuous, staying at the back of the stadium in Malaysia where Liverpool were training as part of their Asian tour.
But in a Red Devils shirt - particularly one with the name of former Everton player Wayne Rooney on the back - he was never going to stay unnoticed for long.
He quickly drew the attention of the whole stand, who started chanting at him to take the kit off.
When he refused, the Reds fans took matters into their own hands, mobbing him and removing the United shirt. In celebration, they sang Kop anthem You'll Never Walk Alone.
But he stuck to his guns, and rather than wear the Liverpool shirt which they tried to press on him he sat in a sulk, before sloping off from the stand.
The boy returned a few minutes later, and seems to have learned the error of his ways - this time around, he was wearing the altogether less contentious shirt of Malaysia's national team.You can watch the joker here.
