Brighton have broken their transfer record to sign Dutch midfielder Davy Propper from PSV Eindhoven in a reported £6m deal.
The 25 year old has signed a four-year deal with the club which won promotion to the Premier League last season.
"Davy is a player with great experience of the Eredivisie with Vitesse Arnhem and PSV Eindhoven," Seagulls boss Chris Hughton said.
"There is no doubting his pedigree, Davy has played a number of matches in the Champions League for PSV, as well as international football for the Netherlands.
"He's a strong competitor as a central midfielder and will complement our existing midfield players, and he is also a really good age at 25; we are absolutely delighted to welcome him to the club."
