Mathew Ryan signed a five-year deal from Valenica in the summer of 2017, for a then club-record transfer fee.
Sydney-born Ryan had a loan spell with Belgian side KRC Genk towards the end of the 2016/17 season, before joining up with Australia for the Confederations Cup.
After playing for Blacktown City and Central Coast Mariners in Australia between 2009 and 2013, Ryan moved to Club Brugge in Europe - where he made more than 100 appearances for the Belgian Pro League team.
Ryan won the Belgian Cup during his time with the club and was chosen as the Belgian Pro League Goalkeeper of the Year in both 2014 and 2015.
The shot-stopper attracted interest from La Liga side Valencia in 2015 and signed a six-year deal with the club, keeping a clean sheet on his league debut against Rayo Vallecano.
Ryan returned to Belgium for a loan spell with KRC Genk during the 2016/17 season and kept 11 clean sheets in his 24 appearances for the club.
Ryan made his international debut for Australia in 2012, and played all three matches in the 2014 World Cup in Brazil, before winning the AFC Asian Cup with the Socceroos in 2015.
Albion's number one made his debut for the Seagulls in their opening Premier League fixture against Manchester City at the Amex, and went on to play every minute of top-flight football for the club during the 2017/18 campaign.
Ryan kept ten clean sheets in 38 games and made a number of fine saves throughout the season, as the Seagulls finished 15th and secured their top-flight status for another season.
The Australian continued his fine form throughout the 2018/19 season, and was named the PFA Bristol Street Motors Player of the Month award for October.
He also represented his country at the 2019 Asian Cup, where Australia reached the quarter finals, where they lost 1-0 to the United Arab Emirates.
