Having been beaten by Ukraine in their tournament opener, the Scandinavians will be eliminated if they lose to Roy Hodgson's side in Kiev.
Hysen, whose son Tobias is in the current Swedish squad, is demanding that Hamren make changes for the crunch clash, believing the coach got things badly wrong in terms of his team selection for the game against the co-hosts.

"You need players like Jonas Olsson and Pontus Wernbloom in there. I don't know what Erik Hamren's philosophy is but I don't seem to share it."
Hysen also insinuated that Hamren was to blame for the lack of organisation and poor defensive play which allowed Andriy Shevchenko to score two headed goals for Ukraine.
"I don't know exactly what system Sweden apply at free-kicks and corners but when you have a guy who is bigger and quicker than you, then you have got to dig in to him, push him away," the 52-year-old Gothenburg native explained.
"You can't lose your marker like they did against Shevchenko. You don't necessarily have to win the duel against the striker but you have got to take him out."
Sweden's vital Group D clash with England is scheduled to get under way at 20:45CET.
