Leinster have won 18 of their last 20 Heineken Champions Cup games (L2), with their only defeats coming last season away to Toulouse in the pool stage and against Saracens in the final.

30 minutes gone.

Gibson runs a good line off him. Saints doing well. They have the advantage.

Biggar breaks!

Into the 22 now.

Saints into Leinster's half.

Over throw and Leinster get it out to van der Flier who smashes over Reinach. Turnover and Naiyaravoro comes away with it

Deep restart and Saints look to run it through Wood. Reinach to Biggar who punts it long into touch.

And Porter is pinged for not rolling away.

Reinach to Tuala off the back, Saints making good ground.
