Fans took to social media on Wednesday night after claiming to have spotted a major Sky Sports gaffe ahead of the Merseyside derby at Anfield.
Liverpool secured a 1-0 win over their arch-rivals Everton thanks to Diogo Jota's second-half goal to move another step closer to winning the Premier League title.
But it was what happened before a ball was even kicked that attracted the attention of a number of fans online.
As Liverpool's famous anthem, You'll Never Walk Alone, was sung around the ground ahead of kick-off, fans watching at home noticed that Sky Sports' sound appeared to be louder and out of time.
