The Spanish side took their biggest-ever away support to a European match as they launched a comeback to beat Celtic 2-1 in Glasgow.

And they were so impressed by their passionate backing, they have taken the unprecedented step of sending each of their fans a note of appreciation.

They stated: "We're still in shock over what we experienced together in Glasgow.

"There are things that, no matter how hard we try to explain them with words, can never truly capture their meaning.

"This story began the day we learned our destination, when Glasgow appeared on the European calendar and thousands of Celta fans began to imagine a night that is now part of our history.

"More than 3,000 of you crossed Europe to be by our side. You left your homes, your routines, and endured many hours of travel to support the team at Celtic Park.

"You pained Glasgow blue and brought a little piece of Galicia to Scotland, with that unique way we have of turning any place into home.

"We know the effort you had to make - the hours of travel, the layovers, the days off work, etc. We know it wasn't easy - that's why seeing you at Celtic Park and recognising you among thousands of people was so moving.

"We want to thank those of you who were able to be in Glasgow and also those who, from home, followed every minute with their hearts there.

"For those who have been traveling miles for decades with the badge pinned to their chests and for those who are just now beginning to discover what it means to be a Celta fan.

"Perhaps that's why Glasgow was so special - two clubs united by two fan bases that are proud of where they come from and understand that roots are carried within, but also defended, shared and celebrated.

"This was our biggest away trip ever. A fact that will forever be part of our history. Thank you for being there, for your effort, and for your unique way of showing love for Celta.

"If there's one thing you've shown us again in Glasgow, it's that wherever we are, we never walk alone."
