Irish rugby fans looking to watch both Leinster and Munster next weekend will be disappointed as they will have to choose between watching both provinces.
The two clubs generally play at different times in the Heineken Champions Cup to cater for an Irish audience but this Saturday Leinster will play Bath from the Aviva Stadium while Munster will head to Castres with both matches kicking off at 5:30pm.
Meanwhile Ulster will welcome the Scarlets to Kingspan Stadium on Friday night while Connacht will head to Perpignan in the Challenge Cup with Ulster kicking off at 7:45pm while Connacht will start at 7pm.
Far from ideal for Irish fans with all four clubs clashing with another province.
