French football’s summer transfer market has its latest headline deal. AS Monaco has agreed to sign Matthis Abline from FC Nantes for a fee of €25 million plus add-ons, with reports placing the total potential outlay closer to €30 million depending on how those variables trigger.
For Nantes, the timing is everything. The club was recently relegated to Ligue 2, meaning this sale goes from a good piece of business to an absolutely necessary one.
What we know about the deal
Abline, 23, has already agreed to personal terms on a five-year contract with Monaco. The agreement between the two clubs was reached around July 22-23, 2026.
The fee structure is a base of €25 million, with add-ons capable of pushing the total toward €30 million. For context, that makes this a record outgoing transfer for FC Nantes, the club now preparing for second-division football after relegation from Ligue 1.
