Joseph Kalulu is attracting interest from Hamburg, with the Bundesliga club reportedly monitoring the Pau FC left-back ahead of a potential move from Ligue 2.
The 21-year-old defender, valued at around €1.00m, has emerged as a rumoured target as Hamburg weigh up options at full-back. The speculation, recorded with an unspecified probability (“?”) on transfer databases, currently centres on a possible deal with Pau FC, though no agreement or concrete offer has been reported.
Kalulu’s contract situation at the French side is unclear, with no expiry date publicly listed, leaving open the possibility that he could become a free agent in the near future. That uncertainty is expected to fuel further rumours, particularly given the relatively modest market value attached to a young defender already drawing attention from a top-flight league.
Born in Lyon on 29 November 2004 and standing at 1.80m, Kalulu plays primarily as a left-back and is left-footed. Eligible for both France and DR Congo, he is listed with dual nationality and has developed entirely within the French system. He moved from Olympique Lyon’s youth ranks through their U17 side before joining AS Saint-Priest’s youth and senior teams, eventually stepping up to Pau FC in 2024.
His rise has been reflected in a sharp increase in market value, climbing from €150,000 in October 2024 to €800,000 by October 2025 and then to €1.00m in December 2025. While specific recent match details, such as opponent, date, scoreline and individual performance, are not provided in the available data, that valuation trajectory suggests consistent progress at Pau in Ligue 2.
If Hamburg decide to firm up their interest, a move to the Bundesliga would represent a significant step up for Kalulu and could prove pivotal in shaping his career, enhancing both his reputation and long-term potential.
