The Italian will take charge of his first game for the Wearsiders following his appointment last Sunday against the Blues.
Benitez told reporters: "The attention is going to be all on him, so it will take a little bit of the attention off me for a change.
"But I'm not worried about the attention on me, just about my team. We need to stay focused and not be watching the other bench.
"We are playing Sunderland, not the manager. I don't think the manager can make that much difference if they do not have the right players."
Chelsea can move back into the top four of the Premier League with a win over Di Canio's side at Stamford Bridge.
