Both clubs have little to play for in terms of league position with Wolves confirmed as champions and Doncaster marooned in mid-table.
"I can't keep the players focused at this stage of the season - they've got to keep themselves focused," he told the Sheffield Star.
"If they aren't going to do that then we might as well not turn up on Sunday. But we haven't done that all season and I'll be disappointed if the players aren't focused.
"I don't care about the result; I want to end on a performance. If we get beat 3-0 or 4-0 and we've performed then I would have to give credit to Wolves.
"If we perform like we've performed in 90% of our games, then I'll be delighted."
