• Northampton 16-43 Leinster• Leinster take control of Pool One
Leinster took control of Pool One of the Champions Cup with a seven-try, bonus-point victory ahead of Saturday’s return at the Aviva Stadium. The four-times European Cup winners had too much know-how for the Premiership leaders whose ambition was undermined by mistakes made under pressure.
Northampton set out to attack with pace, moving the ball immediately from the point of contact to get over the gainline. It yielded them a try for Ashlee Tuala and would have had a second but for Tom Collins knocking on near the line, but their problems lay in slow possession kicked away.
