Leon Balogun has arrived from Mainz, the 28-year-old Nigerian heading to the World Cup and then hitting the Amex Stadium on a free transfer.

Mainz avoided relegation by three points this season, and Balogun played in 14 matches. He had been with the Bundesliga outfit since 2015, and has 16 caps.
Balogun has also spent time at left and right back.
Ezequiel Schelotto just finished his first season as a Brighton right back, playing 28 times, but also moved up the right side. Bruno played plenty there as well, but is 37 years old.
Brighton already had a top-half defense in terms of goals allowed. This should only help that.
