Some elder statesmen of the squad were allowed to depart, while the work of the club's scouting department came to fruition as they also invested in some of Europe's finest young talent.
Keeping Ben White away from the Leeds United and a shrewd free transfer from Liverpool were also highlights of the window for Albion. Scroll down and click through to see their transfer activity.
5. Lars Dendoncker
The 19-year-old midfielder arrived from Club Brugge on a free transfer on a two-year-deal. He's the brother of Wolves player Leander
6. Jan Paul Van Hecke
The defender signed from NAC Breda and has joined SC Heerenveen on loan for the season. “We have been tracking Jan Paul for quite a while. He’s a young talent, a powerful defender who is comfortable on the ball," said Seagulls technical director Dan Ashworth.
7. Andi Zeqiri
An interesting signing for Graham Potter to work with. The 21-year-old striker joined from Swiss outfit Lausanne-Sport for a reported 3.5m. Represented Switzerland from under-16s to under-21s and agreed a contract with Albion until June 2024. Last season he scored 22 times in 37 appearances
8. Jakub Moder
Very highly rated Polish international midfielder and Albion are believed to have paid just over £6m to capture him from Lech Poznan. Agreed a five-year deal but loaned back to Poznan
