Munster have confirmed the signings of South African World Cup winners Damian de Allende and RG Snyman, with Saracens' Matt Gallagher also joining the province for next season.
The trio have signed two-year contracts that will see them remain with Munster Rugby until at least June 2022.
It had been mooted last year that centre De Allende and lock Snyman - both currently playing in the Japanese Top League - would link up with Johann van Graan’s side and it will significantly boost the playing squad for next season.
De Allende played a leading role in South Africa’s winning campaign in Japan, starting six of his seven appearances.
The 28-year-old Cape Town native, who currently plays with Panasonic Wild Knights, has made 47 appearances for the Springboks, scoring six tries and was voted South African Super Rugby Player of the Year in 2015 while playing with the Stormers.
Snyman also featured in every game of South Africa’s successful World Cup campaign, producing a man of the match performance against Canada.
The imposing lock is highly regarded for his athleticism, ball handling skills and towering presence in the lineout.
A product of the Bulls, the 25-year-old has made 23 appearances for South Africa and will make the move from Japanese club Honda Heat at the start of the new season.
The signing of the versatile Gallagher, who can play full-back or on the wing, will offer Van Graan more options in backline.
Irish qualified as his paternal grandfather and grandmother are from Derry and Limerick respectively, the 23-year-old was part of the England U20s World Championship winning side in 2016
In December he lined out against the province in the round three Champions Cup encounter at Thomond Park.
"From a business point of view I am really pleased that Munster Rugby has secured the calibre of these players," Van Graan said.
It's testament to the worldwide standing of this club that two World Cup winning Springboks will arrive here next summer
"In terms of Damian and RG, it’s testament to the worldwide standing of this club that two World Cup winning Springboks will arrive here next summer.
"On a personal level I know them both very well and in addition to being world-class athletes they are great men. They will add value to everything we are striving to achieve at Munster, and I know our supporters will be eagerly looking forward to their arrival.
"Equally, getting Matt on board is fantastic for our backline options. He is an exciting young talent that can play in a number of positions and is from a great rugby pedigree."
