"It's going to be interesting, but the players have to react [in the right way]," Bennett told talkSPORT. "He's in, he's the manager and you've got to go along with it. There won't be a dull moment.
"It will be a roller-coaster. If he comes in and gets results, it's a great decision. It's a massive step up from Swindon to go into the Premier League with seven games to go, but hopefully he can lift the players and the club."
Di Canio is expected to meet the players and hold his first training session at Sunderland today.
