Some Sunderland fans have said they support Paolo Di Canio's appointment, but cautioned that he must keep his political views to himself.
One season ticket holder, Stan Simpson, said some fans would be "wary" about the Italian's appointment but that he respected David Miliband for sticking to his principles.
"I understand Mr Miliband's decision but there is no way we, as fans, would entertain any fascism in our club. As long as he doesn't express any political opinions I can cope with it."
Janet Rowan, another fan, said she thought Di Canio was "very passionate" about the game but said extremist politics "isn't something we want in football".
She added: "I respect David Miliband's views but as fans we have got to support Di Canio."
Sunderland manager Paolo Di Canio denied he was a racist or fascist after his controversial appointment received fresh criticism.
Yesterday's press conference at Sunderland's Academy of Light training base was illuminating in every way but one.
Paolo Di Canio refused to answer questions on whether he is a fascist but said the controversy surrounding his appointment was "ridiculous."
