Brighton manager Chris Hughton has signed seven players this summer

Brighton's £8m bid for FC Zurich striker Raphael Dwamena has been rejected, according to Sky sources.

Brighton remain interested in signing the Ghana international, who joined Zurich from Red Bull Salzburg in January and scored 12 goals in 18 games.

It has been a busy summer for Chris Hughton, who has already signed seven players during the transfer window:

Midfielder Davy Propper from PSV Eindhoven for a club record fee of over £10m, midfielder Pascal Gross and defender Markus Suttner both from German side Ingolstadt, 19-year-old defender Josh Kerr from Celtic, goalkeeper Matthew Ryan from Sevilla, defender Mathias Normann from Norwegian side FK Bodo/Glimt and forward Izzy Brown on loan from Chelsea.

Brighton have also agreed terms over a club-record deal for Colombian winger Jose Izquierdo from Club Brugge.

Sky Sports News reported early on Thursday that the newly-promoted Seagulls were closing on the 25-year-old.

It is understood Brighton representatives met with the player on Wednesday night in a restaurant in Belgium to finalise the transfer, believed to be worth an initial £13.5m, potentially rising to £16m.
