Ulster have a job to do in their home Pro-12 match against current champions Glasgow at the Kingspan Stadium on Friday night.
That's the view of Director of Rugby Les Kiss.
"The fact that they are (the current) champions is a massive warning. No team does that without being good at a lot of things.
"Although this season hasn't panned out as they'd have liked, they know they have to get results in their next games.
"We would be fools to lower our guard and think that they've gone."
