The Nigerian striker is on-loan at United from Shanghai Shenhua.
Ighalo, a boyhood United fan, says that God will direct him over his future.
He told Elegbete TV: "There is no offer on the table yet.
"Because the season is still on and I'm yet to finish my loan deal. I don't just take decisions alone in my life. I have a principle and I have a guideline for everything I do. I always pray to God to direct me.
"I have seen so many tweets about this. I have seen so many people going crazy, (saying) 'go back to China', some say stay with Man United.
"Have you seen me say a word? I don't have anything to say. When the season's finished and I get two offers from the two teams, then I will sit and think about it, pray about it and whatever God says I should do, I will go with that."
Ighalo's current contract at Shanghai Shenhua is set to run until the end of December 2021.
