Diego Moreira played 45 minutes for Chelsea, and his Milan move could earn them €26m
AC Milan have signed the Belgium winger from Strasbourg for a reported €50 million plus add-ons. Because Chelsea sold him to their own sister club in 2024 with a sell-on attached, a large share of that is heading back to Stamford Bridge.

Diego Moreira played 45 minutes of football for Chelsea. It was a Carabao Cup tie against AFC Wimbledon in August 2023, Chelsea won 2-1, and he never appeared for them again. That half of a League Cup match is about to be worth roughly €26 million to the club.
Moreira signed for AC Milan this week from Strasbourg on a contract running to 30 June 2031. He takes the number 22 shirt, which Milan had left empty since Emerson Royal left last summer and which most of the San Siro still associates with Kaká. He is 22 years old, born in Liège, and has four caps for Belgium after switching from Portugal’s youth teams last year.
What Milan are paying
The fee has been reported in several different shapes, which is normal for a deal with this much of it hanging on add-ons. The version most outlets have settled on is €50 million fixed with bonuses that could push the total towards €65 million, and Strasbourg keeping a slice of any future sale. Sky Sport Italia had it as €45 million plus €20 million in add-ons. Sky Sports Deutschland reported €54 million fixed and €11 million in bonuses. The fixed number is the one that matters, and everyone has it somewhere between €45 million and €54 million.
Moreira will earn a reported €3 million net a season. Jorge Mendes negotiated the move, and RB Leipzig had been well advanced on their own version of it before Milan came in.
For Milan this is the second enormous cheque of the summer. They paid Paris Saint-Germain around €74 million for Gonçalo Ramos in June, a club record that comfortably beat the €35 million they gave Lille for Rafael Leão in 2019. Rúben Amorim now has a record striker and a €50 million winger, and Milan open their Serie A season away at Torino on Sunday.
The part Chelsea are enjoying
Chelsea got Moreira for nothing. He left Benfica as a free agent in 2023 and played his 45 minutes against Wimbledon that August. By 1 September he was at Lyon on a season-long loan, and Chelsea recalled him in the January, seven Ligue 1 appearances later. In August 2024 he went to Strasbourg permanently.
Strasbourg are also owned by BlueCo, the Todd Boehly and Behdad Eghbali vehicle that owns Chelsea. So this was a sale from one club in the group to another. The fee was reported at the time as roughly €2 million, and later reporting by DNA Sports put the real figure closer to €8 million. The Standard has it at £1.7 million. Two years on, nobody outside the buildings can say with confidence what Chelsea actually charged themselves.
What is clearer is the clause. The Standard reports that Chelsea kept a sell-on of around 40 per cent, and on the numbers being quoted for the Milan deal that puts their cut at roughly €26.4 million. For a player who cost them a signing-on fee and 45 minutes of squad space, that is a remarkable return on nothing at all.
Why this keeps happening
None of this is against any rule. Sell-on clauses are ordinary, and a club is entitled to insert one when it sells a player it does not want. The reason the Moreira deal reads oddly is the ownership overlap: the seller and the buyer in 2024 answered to the same people, and the price they agreed then decides how much money flows back to Stamford Bridge now.
Both authorities have rules for it. The Premier League’s associated party transaction regime, brought in at the end of 2021 and tightened in 2024, requires deals between linked parties to be struck at fair market value, and player transfers are explicitly covered. UEFA applies its own related-party tests under financial fair play. A fee agreed between two clubs with the same owners is not a market price by default, so somebody has to check whether it looks like one.
The direction of the anomaly is worth noting here. If Chelsea did undercharge Strasbourg in 2024, the sell-on has clawed a good deal of it back, and BlueCo as a group is ahead either way. It picked up a player for nothing in 2023 and is realising somewhere around €50 million for him in 2026, split across two sets of books.
Is he worth it?
That is the question Milan supporters will ask, and the numbers do not answer it cleanly. Moreira made 59 Ligue 1 appearances for Strasbourg across two seasons and scored six goals. Last season was his best: 27 league games, four goals and six assists, plus 11 matches in the Conference League, for 42 appearances and five goals in all competitions.
Those are the returns of a promising 22-year-old wide player, not of a €50 million one. Milan are paying for the two or three years they think are coming rather than the two that have gone, which is how the market works now for anyone under 23 with a Ligue 1 season behind them and a Mendes client list around them.
Chelsea, meanwhile, will bank the money and keep doing this. The satellite-club model has produced a lot of criticism and not much evidence that it does not work.
