Ulster’s Ruan Pienaar believes that Munster will reap the benefits from the appointment of Johan 'Rassie' Erasmus, highlighting the “great knowledge” of the incoming Director of Rugby.

Erasmus will assume the role, a hands-on coaching position, with the two-time European champions from next season and head coach Anthony Foley has welcomed the move.

Pienaar, who worked with Erasmus during the coach's two separate stints with the Springboks, including his role as technical adviser in the 2007 World Cup-winning campaign, says it is a positive move by the Irish province.

“I worked with him a little bit,” Pienaar told RTÉ Sport. “He’s got great knowledge, a good rugby brain.

“I think he’ll add a lot of value to Munster. It's a good signing for them to have someone of his calibre coming in into the coaching staff.”

The current General Manager High Performance of South African rugby won 36 caps for his country and is a widely respected figure within rugby circles.

Munster CEO Garret Fitzgerald outlined Erasmus’ credentials when his signing was announced, describing him as “the stand out candidate” for the newly created position.

"In addition to his extensive playing and coaching experience Rassie's current role has afforded him the opportunity to develop his skill-set further, garnering invaluable knowledge and expertise while implementing an all-encompassing rugby programme which will be key to this role,” Fitzgerald said.
