Brighton announce signing of teenage wonderkid after fending off competition from Chelsea and Newcastle

The right winger has penned a long-term contract with the Seagulls, which runs until 2031. The total fee is reportedly in the region of £21.5million, plus add-ons.

Yohanna was the subject of interest from plenty of clubs around Europe after bursting onto the Allsvenskan scene in impressive fashion last season.

Chelsea, Newcastle and Real Madrid are among a host of sides to have been credited with holding an interest in the 18-year-old over the past few days, but Brighton acted quickly to strike an agreement with both the youngster and AIK.
