This was followed by Munster Senior Cup success and three successive Limerick Charity Cups, and last season Young Munster were a whisker away from winning the Ulster Bank League, in contention right until the end.
Young Munster would like to congratulate the 35-year-old Limerick man on all he has done for the club as he takes the next step forward in his career, coaching at professional level.
President of Young Munster, Jack O'Brien, commented: "We at Young Munster are very grateful for all Mike Prendergast has done for the club during his tenure at Tom Clifford Park.
"From the experience gained in his playing career, Mike has always been able to earn the respect of players, and players wanted to do well for him. You can see that in the silverware we won under his guidance.
"He gathered great squads during his time here and we saw some fantastic rugby which the supporters will always be grateful for."
Prendergast will be involved in the transition to the Cookies' new coaching set-up before he leaves for France.
The former Munster scrum half said: " am massively grateful to Young Munster who created an opportunity for me for the last four years to work in a full-time role with the club.
"This new opportunity coaching at professional level might never have arisen were I not able to work full-time in rugby."
Young Munster would like to wish Mike and his family all the best in the move to France, and look forward to seeing him back at Clifford Park on his visits home.
