Springbok legend Bryan Habana believes new arrivals Damian de Allende and RG Snyman are game-changing acquisitions for Munster.
The 2007 World Cup winner met Reds supremo Johann van Graan last week and got the sense of his compatriot's excitement at his side's potential when rugby gets back under way.
The duo have arrived in Limerick from Japan and are on a three-week break before training resumes ahead of the season recommencing in August.
They will be allowed to go straight into the side's bid to win the Guinness PRO14 - and Habana believes they will make a big impact.
"Munster are probably going through a bit of a development phase since Johann van Graan arrived there," the 124-capped wing wonder said at the launch of his new company MatchKit.co.
"I think the success that Rassie Erasmus enjoyed during a short space of time - there was a lot of expectation.
"Munster not qualifying for the quarter-finals of the Champions Cup was very disappointing, but what they are getting is two World Cup winning, world-class players. Damian De Allende was one of my unsung heroes of Rugby World Cup 2019.
"His ability to not only dominate the collision on attack and defence, his passing - he's probably one of the best passers I've ever seen in the game, off both left and right.
"RG Snyman is someone who again will add brawn and an element of physicality that any team in the world would love.
"So, in this rebuilding phase, I know Johann van Graan will be extremely excited to get those two in."
