Mikel played in Sunday's 0-0 draw at Stoke despite learning a day previously that his father had gone missing on Friday.
Speaking on Sky Sports News, Mikel said he and his family are yet to hear anything regarding his father's whereabouts or who might have taken him, and he made a direct appeal for his father's release. He said: "Please just let him go. He's just an old man, he hasn't done any harm to anyone as far as I know and I don't know why he has been taken."
