Guillermo Balzi (born 23 July 2001) is an Argentine professional footballer who plays as an attacking midfielder for 2. Bundesliga club Holstein Kiel.

Career

Balzi was born in Los Surgentes [es] in the province of Córdoba. A Newell's Old Boys youth product, he made his first-team debut in 2021. When he started in an Argentine Primera División match against San Lorenzo in March 2026, coach Mauricio Larriera's decision to include him was labelled a "surprise" by Argentine newspaper La Capital, with Balzi having previously made just two appearances in the Copa Argentina in that season. Balzi sustained a hip injury in the match, forcing his substitution by Brian Aguirre after 25 minutes.

Balzi spent two seasons on loan with Super League Greece club Levadiakos, scoring 9 goals and making 14 assists in 61 appearances. At the end of the loan, Levadiakos declined the option to sign Balzi permanently for a fee of €1.3 million for 70% of his economic rights. While Balzi's contract with Newell's Old Boys was valid until December 2027, he was not in coach Frank Kudelka's plans.

Balzi joined 2. Bundesliga side Holstein Kiel in July 2026, having signed a contract until June 2029. Holstein Kiel reportedly paid Newell's Old Boys €550,000 for 70% of his economic rights.

Style of play

A creative midfielder, Balzi is left-footed.
