There's plenty of respect between Munster and Ulster.
This week, Ulster announced that they will erect a plaque in their dressing room in memory of Anthony Foley. It reciprocates Munster's tribute to Nevin Spence - the Ulster player who tragically died in a farming accident four years ago.
Ahead of Saturday evening's Champions Cup game at Ravenhill, as there has been and will be at all fixtures in the tournament this weekend, there was a minute's silence for the sadly departed Munster head coach.
There was also what Brian O'Driscoll, on commentary for BT Sport, described as 'spine-tingling stuff'. For the opening minute of the game, Fields of Athenry rang throughout the stadium.
