Brighton have signed 19-year-old AIK and Sweden midfielder Yasin Ayari for £5.2million, according to transfer expert Fabrizio Romano.
That has fueled speculation Albion might now be prepared to sell their in-demand midfielder Moises Caicedo to Arsenal.
The Gunners have already had a £70million bid reportedly rejected.
Manchester United have also been linked with the Ecuador star, 21, who said last year it was his “dream” to play for the Red Devils.
