Munster face a daunting task when they meet Saracens in the Heineken Champions Cup semi-final but will have benefited from the manner of their win against Edinburgh, says Donal Lenihan.

The two-time winners trailed with ten minutes to play but somehow worked field position and then a try to overtake the hosts.

A subsequent rear-guard action held the Scots out and ensured, despite just 39% possession and 36% territory, an 18th semi-final appearance.

Awaiting at Coventry's Ricoh Arena on 20 April are the current Premier champions, who were handsome winners over Munster at the same stage two years ago at the Aviva.

Mark McCall's side, without Owen Farrell, made light work of Glasgow, scoring seven tries in a 56-27 win.

"It’s going to be difficult," Lenihan told RTÉ 2fm’s Game On.  

"They are playing better than last year.

"To win without Owen Farrell just proves the capability and the strength they have in depth. They are exception at the moment, quality up front, and scoring tries for fun.

"That doesn’t mean that Munster can’t win the game. They’ll be better for the experience at the weekend.

"The manner in which Munster plucked victory from the throes of defeat was incredible.  

"The manner in which they closed out the game will stand to them but there will also be a realisation that they are going to have to do better than that to get over the challenge of Saracens."

Lenihan, a former Ireland captain and manager also hailed the impact of a resurgent Keith Earls, the winger who scored twice in the 17-13 victory.

"You can see the hunger that’s there," he said.

"The first try, razor sharp, he just sensed the moment. Edinburgh was distracted, he took the penalty and I think even the Munster players were caught by surprise.

"It’s just his whole preparation, he has changed his diet.

"For years everyone said, ‘look, you need to put on a bit of weight, you’re that bit small’.

"He tried that for years but it never worked for him and he was getting injuries as a consequence of that.

"Two or three years ago he decided he was going to play [his own] way, at his best body weight and he’s been phenomenal both for Munster and Ireland."
