"It is a massive, massive challenge for any club to go down. You've got that complete change of the expectation and the pressure," Black told British media.
"Aston Villa now will be like Manchester United if they go into the Championship... It's a huge challenge but it's not an impossible challenge. It's a really tough division. So the squad has to be constructed properly."
Villa, seven times English champions, could be relegated before they face Manchester United at Old Trafford on Saturday if Norwich City avoid defeat at home to Sunderland in the day's early fixture.
