Herrera has also waxed lyrical about Paul Scholes and Nicky Butt, and will be looking to become another fine central midfielder at United.
"I always looked at other players at Real Zaragoza as that's where I played [as a youngster]. Gus Poyet was a role model for me, and then the national team players like Xavi and Iniesta but so were the United players like Scholes and Butt," he told MUTV.
"They not only played well with the ball, they did great work off the ball too and worked hard to defend when they needed to. They were all big role models for me."
