Town edged past West Brom on Wednesday night thanks to Grant Leadbitter's penalty to set up a last-four meeting with the Gunners, renewing Keane's old rivalry with the north London club.
But with four successive Championship defeats undermining a promotion bid, Keane wants his players to remember their goals for the season.
"We need to get back up the Championship table because that is our bread and butter," he said.
"Getting to the semi-final is a bonus but that is all it is, a bonus - we have to win league matches."
