Albion are trying to lure Iran World Cup winger Alireza Jahanbakhsh to the Amex.
The Seagulls have agreed a fee, believed to be in excess of £1.4 million, with the 21-year-old's Dutch club NEC Nijmegen.
Amir Hashemi, Jahanbakhsh's manager and mentor, told The Argus: "I think it's more than £1.4 million. They are interested.
"We are still busy with negotiations. I have been in England to see the stadium and facilities. We have to think, we are still talking.
"At the moment it's maybe 50-50. It's important Ali visits Brighton himself and talks to the manager (Chris Hughton). He is back from holiday tomorrow and that is the next logical plan."
Hughton's former club Norwich have also been linked with Jahanbakhsh, along with Scottish giants Celtic, but Albion are the only English club to have a bid accepted by Nijmegen.
Hashemi has also visited one other club in Holland and one in Belgium on behalf of Jahanbakhsh, who is attracting interest as well from Spartak Moscow.
Jahanbakhsh won the Golden Bull trophy for best player in the Dutch second division this season after helping Nijmegen regain top flight status with 12 goals and 18 assists.
He has been capped 14 times by Iran, including three sub appearances in last summer's World Cup in Brazil.
