Leinster v Ulster: Match preview The Aviva Stadium plays host to a tantalising all-Irish affair in the Champions Cup quarter-finals on Saturday when Ulster travel south to take on reigning champions Leinster.
Leinster are top of the Guinness Pro14 Conference B and also won five of their six pool stage games in Europe — the only blot in their copybook a narrow defeat against Toulouse.
Ireland relinquished their Six Nations crown in a disappointing defence of their title, but Leinster senior coach Stuart Lancaster believes their returning internationals will be desperate to bounce back for their province. Despite their injury woes, Ulster have won six of their last seven fixtures, including wins over Racing 92, Leicester Tigers and Ulster.
This is why we turn up for work all the time and put in the hours of slog. It is set up perfectly, two provinces going at it.
It takes everyone's attention away. Our players are hugely excited about coming back and playing for this team and trying to represent Leinster well. Hopefully, it's going to be a great occasion. There is literally no doubt about that.
Ulster's most recent victory over their Irish rivals was a win in May
