Kerkez was born in Serbia but chose to represent Hungary at international level, reflecting his upbringing and footballing education. His journey has been anything but conventional. Kerkez first came to broader attention while playing in the youth ranks at Rapid Wien, but it was a bold move to AC Milan in early 2021 that turned heads. Although he never made a senior appearance at San Siro, training with the first team gave the young full-back a taste of elite-level football.

Seeking regular playing time, Kerkez transferred to Győri ETO FC in Hungary and then to AZ Alkmaar in the Netherlands, where he became one of the Eredivisie’s breakout stars, blending fierce overlapping runs with defensive resilience. His pace, stamina, and aggressive style of play drew comparisons to top-tier modern full-backs.

In July 2023, Bournemouth signed him, betting on his potential to shine in the Premier League. Despite his youth, Kerkez slotted in with confidence and energy, earning praise for his boldness on the ball and maturity off it. While still raw in moments, Kerkez combines old-school commitment with new-school attacking instincts. He is a tenacious and forward-minded left-back who fits the mould of a high-intensity player in the modern Liverpool tradition.
