Bournemouth have signed striker Rayan from Vasco da Gama for an initial £24.7m on a five-and-a-half year deal which also includes £5.6m in potential add-ons.
The Cherries saw off competition from a number of other European sides as well as clubs in Saudi Arabia and Russia to sign the 19-year-old Brazilian.
It is Bournemouth's joint-second biggest transfer after the £32m they paid to sign Rayan's compatriot and fellow striker Evanilson from Porto in 2024.
Rayan moves to the south coast as a replacement for attacker Antoine Semenyo, who joined Manchester City for around £65m earlier this month.
