Athletic Club is gearing up for a major transition this summer, as legendary manager Ernesto Valverde prepares to step aside for Edin Terzic. The former Borussia Dortmund boss isn't wasting any time, already mapping out plans to reshape the squad for the 2026-27 season. While the club's famous Basque-only policy limits options, there are still plenty of creative moves to be made—and one potential target has taken them all the way to Scotland.

Enter Zion Pullan, a 15-year-old sensation lighting up Celtic's youth system. This season alone, the young forward has racked up an eye-popping 58 goals and 35 assists, most recently tearing it up with the U17s. His numbers aren't just impressive—they're the kind of stat line that makes scouts sit up and take notice.

Born in the Navarrese city of Tudela, Pullan is eligible to join Athletic thanks to his Basque roots. He's already made three appearances for Scotland's U15s but recently earned a call-up to Spain's U15 side, hinting at his dual-nationality potential. According to La Cantera de Lezama (via ED), he's highly regarded within Athletic's offices, and it's easy to see why.

Described as explosive in one-on-one situations, deadly at attacking space, and a natural finisher, Pullan can play both as a winger or striker. That versatility makes him a perfect stylistic match for Athletic icon Inaki Williams, now 32 and entering the twilight of his career. Club bosses see the teenage starlet as a long-term replacement for the Ghanaian speedster, and they're reportedly eyeing a move as early as this summer.

But Athletic won't have an easy path to securing their man. Pullan is attracting interest from a whole host of clubs across Europe, making him one of the most sought-after young talents on the continent. While it may be tough for Celtic to hold onto their prized academy product, it's far from certain he'd land at San Mames. Still, if the club's hierarchy decides he's their guy, expect them to pull out all the stops to bring him home.
