Chelsea trio Romelu Lukaku, Edouard Mendy and Kalidou Koulibaly are all targets for Saudi clubs.
TMW says delegations from the Saudi Pro League's biggest spenders are in London for talks with player and managerial targets.
Al-Hilal are keen on Lukaku, who spent last season on-loan with Inter Milan - where he is keen to return.
Al-Ahli are targeting Blues goalkeeper Mendy, who has been encouraged to leave by Chelsea management.
And Al-Ahli and Al-Ittihad are both keen on defender Koulibaly, who left Napoli for Chelsea just last summer.
