Newell’s Old Boys has announced the sale of midfielder Guillermo Balzi to German second-division club KSV Holstein. The transfer marks a significant move for the young Argentine talent and provides a welcome financial injection for the Rosario-based club.

Transfer Details

Newell’s Old Boys transferred 100% of Balzi’s federative rights to KSV Holstein. The club received €550,000 for 70% of his economic rights, retaining the remaining 30% for a potential future sell-on. This agreement offers a measure of economic relief for Newell’s. In accordance with Argentinian labor agreements, players are entitled to 15% of the total transfer fee. Guillermo Balzi has generously decided to donate half of his share back to the club, a gesture that Newell’s has publicly acknowledged with gratitude.

Player’s Career Path

Balzi, who emerged from Newell’s youth academy, primarily operates as an attacking midfielder or a ‘mediapunta’. Following his debut in the first team, he was loaned to Greek Super League club Levadiakos for two seasons. During his spell in Greece, Balzi accumulated 61 appearances, scoring 9 goals and providing 14 assists. He recently returned to Argentinian football before Holstein decided to secure his signature permanently. He has signed a contract with the German club that runs until mid-2029.

Historical Significance

This transfer makes Guillermo Balzi only the second Argentinian player in Holstein Kiel’s history. The first was Ariel Zarate, brother of the more famous Mauro Zarate, who played in Germany during the 1993/94 season.

Holstein Kiel’s Preparations

The German club, nicknamed “Die Störche” (The Storks), has been active in the transfer market, adding 15 new players this semester through purchases, loans, and returns from loan spells. The team, managed by Frank Kudelka, is set to resume its pre-season training on Tuesday at the Jorge Bernardo Griffa Training Center. Holstein Kiel is preparing for its fifth and potentially sixth pre-season friendly matches. They have already faced Sarmiento, Argentinos Juniors, Vélez Sarsfield, and Independiente. Future opponents may include regional teams rather than top-division clubs.
