Liverpool fans voiced their opinion of the national anthem on Sunday afternoon, with many supporters choosing to boo ahead of the FA Cup final.
Fans could also be heard jeering as Prince William was presented to the players, along with further boos during the cup's 'Abide With Me' anthem.
It's not the first time the Merseyside fans have booed or sung over the anthem, and while Prime Minister Boris Johnson spoke out to condemn it this week, Liverpool boss Jurgen Klopp defended his side's supporters.
"Of course I have thoughts, but I think in these situations it's always best to ask the question, 'Why does it happen?" questioned Klopp.
"I know our people that well that they wouldn't do it if there was no reason for it. I've not been here long enough to understand the reason for it - it's for sure something historical - and that's probably questions you can answer much better than I could ever.
"The majority of our supporters are wonderful people, really smart. They understand, go through lows, go through highs, suffer together.
"They wouldn't do it if there was not a reason. That's what I know. It's not something I enjoyed but that's (my) answer."
Liverpool ended up lifting the cup after a gruelling 120 minutes of action against Thomas Tuchel's Chelsea side, with a penalty shootout required to separate the two sides.
Kostas Tsimikas was the unlikely match winner, after Alisson saved Mason Mount's penalty moments before.
With two domestic cups now wrapped up already this season, Klopp's Liverpool side can continue their pursuit of a second Premier League title, while also eyeing up the Champions League final against Real Madrid later this month.
