On Iñigo Pérez’s first day as a head coach, he received a supportive call from Andoni Iraola, marking the start of a new chapter in their long-standing friendship. Having known each other for 22 years, both men shared a deep bond, having come through the same academy at Athletic Club Bilbao and played together in the first team.

Pérez, now 36, reflected on their journey, stating, “He wished me luck and said he was there for me.” Their paths diverged as Pérez faced challenges securing a work permit in England, ultimately leading him to sit on the opposite bench at Anfield on match day.

Their story began in 2002, and despite their different personalities—Pérez being more open and Iraola more reserved—their shared intellect and passion for football brought them together. They displayed natural leadership qualities, often influencing their teammates on and off the pitch.

Both players transitioned into coaching, with Iraola starting his career in 2018 and Pérez following suit. Their professional trajectories aligned when Iraola invited Pérez to join him at Rayo Vallecano, where they thrived as a coaching duo.

However, Pérez faced a setback when his work permit was denied, forcing him to return to Spain while Iraola excelled at Bournemouth, leading them to European competition. Despite their separation, their collaboration continued through phone calls and shared philosophies.

As they prepare to face each other at Anfield, both coaches express pride in each other's accomplishments. “I am so, so happy for Iñigo,” said one staff member, emphasizing the respect and affection within their friendship. This match not only represents a professional rivalry but also a celebration of their enduring bond in the world of football.
