Athletic Bilbao once again showed their admiration and affection for Celtic during their 2-0 win over Rangers at the San Mamés last night, securing their place in the semi-finals of the Europa League.
The victory, which saw Athletic Club progress with a 2-0 aggregate score, it also served as another heartfelt tribute to Celtic, who they share a deep respect for.

As the Basque side celebrated their progression to the next round, the sight of Celtic flags in the stands was hard to miss.
A number of Athletic Bilbao supporters proudly waved the green-and-white flags even before kick-off, a gesture that once again reflected the strong connection between the two sets of fans.

The respect between the fanbases is something that has shared with both sides, with a mutual respect.
On the pitch, Athletic Club’s win over Rangers was a well-deserved one, with Oihan Sancet scoring from the penalty spot and Nico Williams adding a second goal to seal the result.

For Celtic fans, it is hard not to feel a sense of pride in the fact that the Hoops has such a respected and friendly following in the Basque region.

The ongoing support from Athletic Bilbao fans means a lot to the Celtic support. It shows that football is about more than just the game – it’s about shared values, history, and standing together.
As Bilbao now get ready for their semi-final match against Manchester United, Celtic fans will surely keep supporting their Basque friends, just as they always have.
