West Ham United have completed the signing of Nice defender Jean-Clair Todibo on an initial season-long loan deal with an obligation to buy the Frenchman for £34.22m (40m euros) in 2025.
Julen Lopetegui's side saw off competition from Italian club Juventus to sign Todibo, 24, who has two senior caps for France.
"It is a dream come true to play in the Premier League, the best league in the world," said Todibo.
BBC Sport understands the Hammers have also agreed a deal to sign Manchester United's Aaron Wan-Bissaka to further bolster their defence.
The 26-year-old full-back, who was left out of Manchester United's squad for the Community Shield fixture against Manchester City on Saturday, will have a medical with the Hammers on Sunday.
