Villadelprat, known for his tenures with teams like Tyrrell, Benetton and Prost, has now called on Red Bull to sever their connection with Marko due to what he deems as Marko's negative presence within the team.
"Take Helmut Marko away from the f****** team," he told PlanetF1.
"Every time he opens his mouth, the only thing he's doing is hammering. It's an area that you don't need to talk about because, if things don't go well and things are tough for a driver, you don't need somebody telling you that you're useless.
"When you're a manager and you have a lot of people working with you, there are various ways of working. You have some people that you need to be behind hammering them, that's the way that you motivate them, but you have people that you don't need to hammer.
"When they make a mistake, you pick up the pieces and put them back again, so help him to get back into the place. That's what a manager should be doing, that's what Christian [Horner] is supposed to be doing.
"But, at the moment, right now, there is no better choice than Checo [Perez] for Red Bull."
