Bolton have a difficult end-of-season run-in, with matches against fellow top-eight opposition in Stockport, Cardiff, Stevenage, Huddersfield and Bradford to come in their final eight games.
Asked whether he was running out of attacking options having failed to score against Doncaster, Schumacher added: “We’ve scored about 10 goals in the past four games, so no don’t think we’re running out of options.
“We had three strikers on the pitch today. Mason Burstow’s got 11, Johnny Kenny’s got one and Sam Dalby’s got 12, so we’ve got goals in the team.
“But we just didn’t manage to connect with the chances that we had.”
