Hamburg are being linked with a move for Pau FC left-back Joseph Kalulu, with the Bundesliga side reportedly monitoring the 21-year-old defender amid growing interest in his progress in France.
According to data sourced from Transfermarkt, the rumoured switch from Pau FC to Hamburg currently carries an estimated probability of 30%, underlining that talks remain at an early and speculative stage rather than an advanced negotiation. Kalulu’s market value is listed at €1.00m, a figure that could appeal to clubs seeking a relatively low-cost defensive reinforcement with development upside.
Kalulu, born on 29 November 2004 in Lyon, represents both France and DR Congo at nationality level and is naturally left-footed, operating primarily as a left-back. He wears the number 3 shirt for Pau FC, who compete in Ligue 2, and has seen a sharp rise in his market value over the past two seasons, climbing from €150,000 in October 2024 to the current €1.00m valuation by December 2025. That trajectory reflects his emergence as a regular at senior level after stepping up from the French lower divisions.
Pau signed Kalulu from AS Saint-Priest in 2024, following earlier spells with AS Saint-Priest B, AS Saint-Priest U19 and the youth ranks at Olympique Lyon, including their U17 side. This pathway through Lyon’s academy system and the competitive environment of Ligue 2 has helped shape him into a modern full-back, comfortable defending the flank and contributing to build-up play on his preferred left side.
With no contract expiry data publicly available in the provided information, observers have also speculated that Kalulu’s situation could evolve towards a potential free-agent scenario, which would further intensify interest from abroad. Should a move to Hamburg materialise, a step into the Bundesliga would mark the most significant leap of his career to date and could prove pivotal in defining his long-term reputation and potential at the top level.
