Nabil Fekir has completed his move to Real Betis from Lyon for an initial £17.75m.
The deal for the France midfielder also included add-ons of £9.8m and a 20 per cent sell-on clause for Lyon.
Nabil brother's Yassin moves with him to Betis for a 50 per cent future sell-on clause.
Last summer, Fekir looked set to join Liverpool for £53m but the move broke down with reports claiming the 26-year-old had failed a medical.
Now the Ligue 1 club have been forced into the sale of their captain, with his contract set to expire at the end of the coming season.
