IT MAY NOT have been the most convincing performance but Donncha O’Callaghan believes Munster’s narrow win over Ulster on Friday night was exactly what his side needed ahead of the return of the European Champions Cup next week.

Munster moved to the summit of the Guinness Pro12 with the 21-20 victory in the inter-provincial clash at Thomond Park.

O’Callaghan admits the home side were fortunate to come away with the points but insists it was an ideal work-out ahead of Clermont’s visit to Limerick.

“We’re just delighted to get a win really,” the Munster captain said. “It was tough opposition and a step-up from what we normally expect in the Pro12 but it will hold us in good stead heading into the next week.

Munster have now won seven consecutive games in both domestic and European competition but were caught cold by a purposeful Ulster start last night. The visitors enjoyed the better of the opening exchanges and manufactured a healthy 12 point advantage inside the opening quarter.

While O’Callaghan admits it was a disappointing start from the hosts, it serves as a lesson and accentutates something they need to improve on in the week ahead.

“It was poor from us, they hit their straps and it’s definitely something we’ll have a look at because it was a slow start,” the second-row said. “I thought we were going to come out of the blocks firing but we didn’t and that’s disappointing from us because at home in Thomond you want to get off to a fast start but to be fair they put us under pressure.”

Tries either side of half-time from Robin Copeland and Duncan Williams, as well as three Ian Keatley penalties, turned the game on its head and was enough despite a late rally from Ulster.
