Lyon, Saracens, Cardiff Blues, Glasgow Warriors
After two consecutive wins, Saracens went out last season to eventual winners Leinster. They will be hurting from that and have started the Premiership in great form. Glasgow are also doing well in the Pro 14, and will want to improve on last season when they finished bottom of their group.
Player to watch
Saracens’ Liam Williams always does something with the ball.
