Sporting CP completes €18M transfer of Sergi Altimira from Real Betis

Sporting CP has locked down one of the more quietly coveted midfielders in European football, signing 24-year-old Sergi Altimira from Real Betis for a fixed fee of €18 million. The deal, finalized in late June 2026, includes performance-related add-ons that could push the total package to somewhere between €20 million and €22 million.

Altimira’s new contract runs through 2031 and carries a release clause of €80 million.

The deal structure and the players behind it

Super-agent Jorge Mendes facilitated negotiations on Sporting’s side. Real Betis negotiated a 12.5% sell-on clause, meaning they retain a stake in Altimira’s future market value. Altimira is a product of La Masia, Barcelona’s legendary youth academy, which means the Catalan giants are entitled to a solidarity payment through FIFA’s training compensation mechanism. That payment is expected to land around €400,000.

Why Sporting beat out the competition

Eintracht Frankfurt submitted an offer of €18.5 million plus performance bonuses back in August 2025, and it was rejected. RB Leipzig also expressed interest, adding another Bundesliga club to the list of suitors who ultimately came up empty.

What this means for the market

The Betis sell-on clause of 12.5% adds another wrinkle for any future suitor. Any club looking to sign Altimira from Sporting would know that a portion of the fee flows back to Seville, effectively making the real cost higher than the sticker price. Between the base fee, add-ons, sell-on percentages, solidarity payments, and agent involvement, the €18 million headline number only tells part of the story. The actual financial web connecting Sporting, Betis, Barcelona, and Mendes’ agency is considerably more intricate.
