United States star Reggie Cannon is the subject of interest from several Premier League clubs.
The likes of Burnley, Stoke City, West Bromwich Albion and Birmingham City are chasing his signature.
A full international who is only 25, Cannon is a free agent this summer after leaving Boavista.
He has departed the Portuguese club over a dispute regarding unpaid wages this past season.
There are offers for him to go back to the United States, but the Premier League will appeal a great deal.
Cannon, who is the grandson of atmospheric scientist Dr Warren Washington, stated he was not paid on time in three years at Boavista.
