Three Saudi clubs are interested in Troost-Ekong.
William Troost-Ekong, a Nigerian defender, could transfer to Saudi Arabia this summer, according to TalkTalk Nigeria.
According to BBC reporter Oluwashina Okeleji, three Saudi clubs have expressed interest in the center back.
Troost-Ekong was in top form for PAOK in the preseason.
The 30-year-old has fully recovered from the injuries he sustained during the 2023 Africa Cup of Nations.
The former Watford player was also connected with a Saudi club during the 2023 AFCON championships, which will be hosted by Cote d'Ivoire.
Troost-Ekong was chosen the Most Valuable Player (MVP) of the competition.
He scored the game-winning goal as PAOK overcame Bosnian club FK Borac Banja Luka 3-2 in a UEFA Champions League second round qualifying match last week.
