Robbie Keane is considering offers from the United States, Australia and England but is expected to sign for a Championship club next week.
The 36-year-old striker is a free agent following his exit from Major League Soccer side LA Galaxy in November.
Preston is his likeliest destination but Leeds and Brighton are also among those that are believed to be interested. Shamrock Rovers are also being talked about.
Keane, a record appearance holder for the Republic of Ireland, has played for 10 different clubs during his career, including Liverpool, Tottenham and Celtic.
