Brighton have signed Iran winger Alireza Jahanbakhsh from Dutch club AZ Alkmaar for an undisclosed club record fee, reported to be £17m.
The 24-year-old, who has signed a five-year deal, becomes the Premier League club’s eighth major summer signing..
Jahanbakhsh played in all three of Iran’s games at this summer’s World Cup in Russia.
He started the 1-0 win over Morocco and the 1-1 draw with Portugal, while he came on as a substitute in the 1-0 defeat by Spain as Iran narrowly missed out on reaching the knockout stage.
Jahanbakhsh, who has been at Alkmaar since 2015, has won 41 caps for Iran.
“Ali is a player that we have been aware of and monitored for a few years,” continued Hughton, whose side finished 15th in the table in 2017-18 to secure a second successive season in the Premier League.
“I am now very much looking forward to working with him.”
Brighton start the 2018-19 season away to Watford on 11 August.
