"I've never dated or even met David Moye's Daughter so that isn't the reason for my absence in games," the 21-year-old Tweeted on Friday.
"I would like to stop all these false accusations .. I will play for Manchester United when my manager feels I'm ready."
Zaha, capped twice by England, signed for United from Crystal Palace in January for 15 million pounds ($24.5 million), but remained at the south London club until the end of the season.
He is yet to make a league appearance for United, having only played in the Community Shield win over Wigan Athletic and in a League Cup victory over Norwich City, fuelling speculation on social media that his omission from the team was linked to a relationship with his manager's daughter.
