One United fan has recalled mixing with the Newcastle United manager recently.
"We were standing in the line and he just asked us what teams we supported," Durham University student Jack Leach told the Chronicle of the Newcastle manager's visit to the university's state of the art facilities at Collingwood College.
"I was in front of him and told him I was a Man United fan and he hit me on the head.
"It was quite funny."
Benitez, of course, is tied to United's bitter rivals Liverpool thanks to his past Champions League triumph with the Reds.
