CELTIC fans have been hailed as "the best in the world" by Spanish onlookers following their appearance at the Bernabeu last night.

It may not have been a party on the field for the Hoops, as Ange Postecoglou's men were comfortably beaten 5-1 by the kings of Europe. 

However, in the stands, the Celtic faithful were in full voice throughout despite the heavy loss.

Celtic supporters waited inside the ground for some while after full-time, as they took in the iconic stadium.

As they exited the ground, though, they remained in fine voice, signing their version of 'Bella Ciao'.

A video emerged on social media of Hoops fans pouring out of the Bernabeu.

As the large portion of the Celtic fans kept their party going, one Spanish observer told a fan that the Hoops' travelling support are among the best in the world.

Asked about the club's fans after the match, Postecoglou was also full of praise.

He said: “Their support is unbelievable. Obviously we’ve lost 5-1. I don’t think anyone enjoys that kind of defeat. Their reaction after the game was not just them trying to make us feel good, I think they can appreciate what the players are trying to do.

“That gives us, and certainly me, massive motivation to reward them. To make sure we qualify again next year and next year we perform better and give them more moments like Jota’s. Because that is what they deserve.

"Ultimately I am responsible for the approach we have taken and how we have gone about things and I would have wanted to repay them for their support.”
