Donncha O'Callaghan lambasts 'totally unacceptable' Munster display in shock loss at Zebre

Donncha O'Callaghan branded Munster's performance as "totally unacceptable" after the province came unstuck at Zebre in Saturday's United Rugby Championship clash.

Munster led by 13 points at half-time but ultimately succumbed to a 42-33 URC loss at the Stadio Sergio Lanfranchi in Parma against a Zebre side that propped up the URC table last season.

Speaking on RTÉ Sport, former Munster second row O'Callaghan expressed his frustration about the way Munster went about their task.

"You don't want to take away from the fact that Zebre were full quality for it but it was totally unacceptable from Munster," said the RTÉ rugby analyst.

"But Munster's performance there was completely unacceptable."

"There were warning signs from last week," he added, referencing
