Connacht got their European Champions Cup campaign off to a perfect start last night.

They fought back from a 10-point interval deficit to defeat four-time European champions Toulouse 23-21 in a night to remember at the Sportsground.

Before that, Leinster picked up a bonus point win with their 33-15 victory against Castres at the RDS.

Munster and Ulster will be hoping to follow in the footsteps of Connacht and Leinster and kick-start their campaigns with wins later.

First up, in Pool 5, Ulster go to Ian Madigans Bordeaux-Begles at 1pm.

After their derby-day disappointment against Leinster at the Aviva Stadium last week, Munster travel to Racing 92.

The game also sees them meet up with former Munster hero and Racing assistant coach Ronan O'Gara.
