According to TEAMtalk, Nias will refuse invitations from teams such as Middlesbrough in order to go overseas.
Nias’s contract with Everton expired this summer and he has not yet found a new owner.
Although Nias has not developed smoothly in recent seasons, as a free agent, he has attracted the attention of many teams.
Both Derby County and Middlesbrough have expressed interest in Nias, but teams from the Middle East have made generous offers for him, and clubs in Qatar, Saudi Arabia and the United Arab Emirates have all made offers.
Nias, 30, joined Everton at a high price from Lokomotiv Moscow during the 2016 winter transfer window, but he did not get too many appearances in Toffee.
