Director of Rugby Les Kiss 'frustrated at times' despite Ulster win

Ulster Director of Rugby Les Kiss admits to being "frustrated at times" during his side's 40-17 Pro12 bonus-point win over Zebre in Parma.

The Irish province made hard work of their success for some periods of the match, leaving Kiss to offer "a few choice words" to his players at half-time.

"We put ourselves under pressure and half-time couldn't come quickly enough for me, but we responded well. We took our foot off the pedal but finished strongly in the second part of the second half," said Kiss.
