Ulster's director of rugby Les Kiss says his team weren't clinical enough and didn't work hard enough as they slipped to a surprise home defeat by Munster in the Pro12.
The home team went into the game after four straight wins in December but Ian Keatley's nine points proved enough to earn Munster a 9-7 win in Belfast.
"We gave them enough opportunity to hang in there and our error-rate was too high. It's a disappointed dressing-room," said Kiss.
"Another three or five points would have been ideal before half-time. We probably just weren't clinical enough and probably didn't work hard enough to create pressure."
