Tunisia forward Youseff Msakni is attracting Premier League interest.
Msakni, who currently plays for Al Duhail in Qatar, has been in England this week trying to finalise a move ahead of the January market.
Talks have been held with Watford, Cardiff City and Brighton.
The three clubs are reported to be considering an initial six-month loan for the 28-year-old, with a view to a permanent deal, after the striker missed the World Cup in Russia with a knee ligament injury.
Msakni scored 23 goals and provided 14 assists in 20 league games last season.
