In the grand Palacio Ibaigane, the headquarters of Athletic Bilbao, a flag is preserved that symbolizes the unique bond between the Basque club and Newcastle United. This connection, forged over 30 years ago, is set to be rekindled on the Champions League stage when the two teams face off this week. The story dates back to 1994 when an Athletic fan missed his transport back to Bilbao and was stranded in Newcastle after a UEFA Cup match. A local family took him in, and this act of kindness spread to Bilbao, creating a warm atmosphere during the return leg.

During the second match in Bilbao, Athletic triumphed over Newcastle on away goals, and fans flooded the pitch, not to fight, but to applaud the visitors. For those who were there, it was a unique experience they describe as the best they’ve ever had. The warm welcome and absence of hostility remain etched in everyone's memory.

The friendly relations between the two clubs have deepened over the years, with Athletic participating in Rob Lee’s testimonial match in 2001, and meeting again in a friendly in 2022. On that occasion, Athletic gifted Newcastle a flag symbolizing their friendship.

Julen Izagirre Garnica, a passionate Newcastle fan from Bilbao, describes how he has been in love with the club for 18 years, and the connection with Athletic is something he greatly values. According to him, both cities have a strong regional identity and pride, which makes them unique.

Ahead of the Champions League match, Newcastle fans plan to return the gesture by preparing a flag for Athletic, symbolizing the bond between the two groups of supporters. This is a way to celebrate the shared principles and warmth that have endured for over 30 years.

Analysis: The relationship between Athletic Bilbao and Newcastle United is a rare example of heartfelt friendship in the football world, often dominated by rivalries. It is a testament to how sport can unite people from different cultures and regions.
