Kristensen, 24, headed home from a corner in the 51st minute — his third Serie A goal of the season — to confirm the victory at the Bluenergy Stadium.
The goal came five months after returning from a serious thigh muscle injury that sidelined him from October, and it reinforced what Udinese coach Kosta Runjaic has long been saying about the player's ability to influence matches from centre-back.
According to La Gazzetta dello Sport and Tuttomercatoweb, Kristensen is one of two defensive signings Milan are planning for the summer, alongside Lazio's Mario Gila. The two profiles are seen as complementary rather than alternatives — Gila as a more technical, progressive option and Kristensen as the physical, aerial presence. Kristensen stands 198 centimetres tall and has captained Udinese in their last two league fixtures.
Sporting director Igli Tare has held discussions about the player since the summer of 2025, with the Rossoneri monitoring him throughout a season that has produced 27 combined Serie A and Coppa Italia appearances, three goals and consistent starting status.
Head coach Massimiliano Allegri has reportedly signed off on the acquisition, seeing Kristensen as an ideal fit for the right braccetto position in a three-man defensive line.
Allegri himself has publicly deferred questions about the summer market until Champions League qualification is secured.
"For now, I am not thinking about the transfer market. Once the objective is reached, we can evaluate everything."
The obstacle is Udinese's valuation. Kristensen was signed from Danish club Aarhus in 2023 for around €3 million, but his value has since multiplied. Udinese are working on an extension that would protect the asset and are under no financial pressure to sell.
Juventus have also been tracking him, and English clubs have made preliminary enquiries. Milan's advantage, if confirmed, would be the Champions League bait — and Allegri's specific desire to work with the player.
