Zaha was a late addition to England's squad for the friendly in Stockholm and was introduced for the final few minutes of the 4-2 defeat.
However, with the 20-year-old also eligible to play for the Ivory Coast, Holloway fears Zaha is being pressured into pledging his international allegiance to England.
"Was it because the England manager wanted to see how my Crystal Palace striker would handle international football just a few days after his 20th birthday?
"If so, why the hell did he give him just four minutes of action in Sweden in a friendly that had already slipped away from his team? Every other substitute got 20 minutes. And that worries me.
"I've got a horrible feeling that the reason Wilfried was given a first Three Lions cap because it was a way to pressurise a young lad into committing himself to England rather than the country of his birth."
