**The countdown to Boxing Day and the festival of Guinness PRO14 derbies continues apace.** And the latest entry in our 12 Days of Derbies celebration sees us return to Ireland for a interprovincial clash back in 2018 that went down in Championship history. Munster showed no mercy as they handed Ulster their biggest ever defeat in the Guinness PRO14, running in nine tries as they romped to a comprehensive 64-7 success. The two sides are due to renew their rivalry in Round 10, which will also their first game of 2021, and this remarkable result from yesteryear will still be fresh in the memory of many. **Munster 64-7 Ulster, Thomond Park, Limerick - September 28, 2018** Alex Wootton was only a late replacement for the injured Mike Haley before the game but he immediately set the tone with a rapid break down the left wing after breaking a tackle. Wootton cut inside and found the on-rushing Dan Goggin to open the scoring with a scything score with only five minutes on the clock as Joey Carbery added the extras from the tee.
