Milan have confirmed Christopher Nkunku’s move to RB Leipzig on loan with an option to buy until 30 June 2027. The statement is dated 25 August 2026. The Frenchman arrived in Milan on 30 August 2025. In between there is one season, and a sum worth doing in full, because it shows how a loan works when it is not about developing a young player but about fixing a valuation mistake.

Three hundred and sixty days
The calendar is the most eloquent part of the story. On 30 August 2025 Milan announce Nkunku permanently from Chelsea, on a five-year deal until 2030. The reconstructions at the time spoke of 37 million euros plus 5 million in add-ons and wages of around 5 million net a season: press figures, never confirmed line by line.
On 25 August 2026 the same club send him out on loan. One season: 35 appearances, 8 goals, 3 assists. In another context those numbers would be judged as reasonable. They become insufficient when set against the cost of the deal and the job the player was meant to do.
The change on the bench did the rest. Ruben Amorim identified a group of players outside his plans, and according to the Italian and Portuguese press Nkunku was in that group along with Fikayo Tomori, Youssouf Fofana and David Odogu. When a new coach leaves out a player bought for forty million a year earlier, the club has three options: keep him idle, sell him cheap, or loan him.
Why the loan is the third road
A loan with an option to buy, in cases like this, is not a way of letting somebody mature. It is an accounting and a sporting instrument at once, and it does three different things for three different parties.
For Milan it suspends a problem without closing it at a loss. The club sheds half of the salary for a season (Leipzig cover 50% of it, according to the Italian press), banks a loan fee, and keeps alive the possibility that somebody else pays for the registration. The overall saving estimated by the press is around 8.1 million, not the full cost of the salary. The annual amortisation charge of the original signing, estimated a year ago at around 7.4 million, stays on the books until the option is exercised: which is why clubs prefer a high option and a low loan fee to a clean sale.
For Leipzig the risk is close to zero. They take a player they know, in a role they know how to use, without committing capital. If it works they buy him, if it does not they send him back.
For the player it is the chance to play regularly again at twenty-eight, the age at which a season on the bench costs more than any other.
What Nkunku was at Leipzig
The numbers are worth recalling, because they are the reason for everything. Between 2019 and 2023 in Saxony he racked up 172 appearances and 70 goals. In 2021-22 he was voted Bundesliga player of the season with 20 league goals and 13 assists, and the following year he shared the top scorer award with 16. Two German Cups in between.
The reason he thrived in that context is understandable even from a distance. Leipzig’s football in those years gave him what he needs: open space ahead, high turnovers, quick transitions and the freedom to start from behind the striker rather than as the reference point. Nkunku is not a centre forward who plays with his back to goal, he is an attacker who arrives in the box from deep.
In Milan, in a different context and with a less defined role, that trait found less room. It is not a question of willingness: some players only work inside a certain kind of game.
The risk of going back
That said, returning is never the same as staying. Three years have passed, the player is twenty-eight and not twenty-five, and above all the club is not the one he left. Ole Werner is no longer on the bench, dismissed despite a third place and Champions League qualification: since June 2026 Leipzig have been coached by Martín Demichelis, on a contract until 2028.
A new coach means new ideas, and no guarantee that the role which made Nkunku dominant still exists in the same shape. Going home works when home has stayed the same: here it is a bet on a resemblance, not on continuity.
What Milan are left holding
If the option is not taken up, in the summer of 2027 Milan will find themselves with a twenty-nine-year-old on three remaining years of contract and two seasons without continuity behind him. That is the scenario that makes these loans less painless than they look: an option is not an obligation, and whoever grants one knows it may never be exercised.
The honest way to read the operation is this: Milan have bought the chance to repair a mistake, and paid for it with a season of waiting. It is neither a loss nor a gain. It is the time it takes to find out whether somebody else sees in the player what the club saw a year ago.

Frequently asked questions
What kind of deal takes Nkunku to Leipzig?
A loan with an option to buy until 30 June 2027. That is what Milan's official statement of 25 August 2026 says, and it contains no figures at all.
How much is the operation worth?
The Italian and German press talk about a loan fee between 3.5 and 4 million euros and an option set at around 28 million, for a total close to 32. These are journalistic reconstructions: neither club has published any numbers.
When did Nkunku join Milan?
On 30 August 2025, permanently from Chelsea, on a contract until 30 June 2030. The loan to Leipzig therefore comes almost exactly a year later, five days short.
What did Nkunku produce at Milan?
Thirty-five appearances, 8 goals and 3 assists in one season. Those are not the numbers of an outright failure, but they are a long way from the ones that justified the investment.
Why Leipzig of all places?
Because it is where he played the best football of his career: 172 appearances and 70 goals between 2019 and 2023, the Bundesliga player of the season award in 2021-22 and a shared top scorer title the following year.
