At the time of Propper's move, it was the record transfer fee that the Seagulls had paid for a player.

The 25-year-old played more than 250 senior games in his homeland, including Champions League and international appearances - and scored 43 goals from midfield.

He helped PSV win the Eredivisie title in his first full season at the club in 2015/16, after signing from Vitesse Arnhem.

Born in Arnhem, Propper began his career with his hometown team Vitesse and made his debut in 2010.

He played more than 150 times for the Dutch top-flight side and appeared for them in the Europa League; before securing a move to PSV in 2015.

First called up by the national team in 2013, Propper won his first international cap against USA in June 2015 and has been named in the international squads regularly since.

He has also represented the Netherlands at under-19 and under-21 level, and his two brothers Robin and Mike are also professional footballers.

Propper made his Albion debut in their opening Premier League game against Manchester City at the Amex, and went on to make 35 top-flight appearances for the Seagulls as the club secured their top-flight status for the following campaign.

The Dutchman featured regularly during the 2018/19 and 2019/20 campaigns, the latter in which Albion secured a club record points tally of 41.
