Munster are still hurting "mentally" from defeat to Leinster but attack coach Stephen Larkham denies their performance in the Guinness Pro14 final was flat.

Leinster won 16-6 with the visitors to the RDS creating few attacking chances.

Indeed, had the four-in-a-row champions been a bit more clinical they could have easily added at least two tries to their tally.

It was the fourth knock-out game in a row that Leo Cullen’s side comfortably held their rivals at arm’s length.

"I wouldn’t say we were flat," Larkham told RTÉ Sport.

"It was one of those games that just crept away from us.

"We’ve spoken a fair bit about belief this morning. It’s a key message. Are they better than us? They worked better than us on the day.

"There are some stats, if you look at it, they made more mistakes than us. There were some key moments that went their way but it was fairly evenly matched throughout the day.

"We’ve got the game plan and the skill. We just got beaten on the day by better execution." 

Top 14 leaders going Toulouse are the visitors to Thomond on Saturday with the winner through to the Heineken Champions Cup quarter-final.

Asked if a result against the Ugo Mola’s charges depended on channelling the hurt from Saturday night, he said: "You’ve got to be careful with emotion.

"It was a big game last week and we built ourselves up through the week and I really did feel that we peaked energy-wise during the game and it’s tough to come back from that.

"You put a lot of energy into that. We gave the guys a couple of days off to try and reinvigorate them today.

"This morning has been a slow start, we’ve been cruising through the stuff that we want to implement this week. This afternoon will be a good session and we’ll get a really good feel for where the team is at.

Moods swing ahead of Munster and Leinster Euro tasks

"We don’t want to peak too early; we know it’s a final for us. We certainly want to build and we want to be mentally and physically refreshed come Saturday as opposed to right now.

"I think some of the guys are still struggling, some of the guys are just about over it but it’s tough.

"We’ve had a couple of games against Leinster now that haven't gone our way. They’ve been close games. We’ve been the team that has pushed Leinster more than anybody else in the big games with full squads out there.

"It hurt, we’re still picking up our mental state there at the moment.

"It’s fair to say we are not quite there. We are not ready to play a game this afternoon or tonight but it’s expected and by the end of the week we’ll have built nicely." 

Captain Peter O’Mahony is a facing a race against time to be fit for Saturday’s game after suffering a "deep laceration to his thigh" against Leinster.

"It’s really unknow at this stage," said Larkham. "We will make a decision later in the week.

"He’s very important to our plans. We want to give him as long as possible. We don’t know today."

Munster also confirmed the signing of Jason Jenkins, a South African forward who will join ahead of next season.

Currently playing with Toyota Verblitz in the Japanese Top League, the 25-year-old can play in the second or back row.

Jenkins was capped by the Springboks in 2018 against Wales.

"First and foremost, experience," the Australian World Cup winner said when asked what he will add to the squad, who lose CJ Stander to retirement at the end of the season.

"Springboks, Springboks A, experience in Japan, albeit in a different competition. He played for the Bulls in South Africa. He's a South African forward, he knows the tough stuff. He gives us coverage in all positions in the back five.

"I think he's going to bring experience to all of those players, whether they are younger or older in the team." 

Meanwhile, Fineen Wycherley and Diarmuid Barron have signed contract extensions, while academy quartet Jack Daly, Josh Wycherley, Thomas Ahern and Jack Crowley have moved up to the senior squad.
