The Champions Cup began with Saracens inflicting a first home defeat on Toulon, Connacht's fightback to beat Toulouse and Scarlets extending Sale's losing streak in Europe to 12. But who was player of the week?
Bundee Aki
Ireland must be thinking October 2017 can't come around soon enough when Aki would be Irish qualified. He was outstanding for Connacht against Toulouse, in creating the first try, getting involved at the breakdown and scoring the try that led to the match winning conversion.
Owen Farrell
Saracens didn't know what they were missing until the out-half started his first game of the season and pulled the strings to inflict a first home defeat on Toulon in Europe. He began the scoring with a penalty three minutes in and ended it with a penalty a minute from time that cemented their victory.
Louis Picamoles
The Frenchman drew two tacklers before his backhanded flick put Calum Clark in to score a try in the opening minutes in Northampton's win over his former club, Montpellier. He showed brilliant pace to make a 40 metre break which led to a penalty and his defensive ability at the breakdown showed further quality.
Scott Williams
The centre provided the moment of the match as Scarlets beat Sale, a brilliant behind the back offload after a break from his midfield partner Jonathan Davies. Considering he was in a moon boot for the first half of the week, he did well and his man of the match performance ended with calls from Scarlets coach Wayne Pivac for an international call up.
Jonny Gray
Glasgow have spoken about making strides in Europe in Gregor Townsend's last season and Gray epitomized their effort on Friday as they put Leicester Tigers to the sword. A dominant display by Gray and the forward pack set the platform for victory, providing quick ball and putting immense pressure on Tigers which led to two intercept tries.
Joey Carbery
There was a time when Leinster shuddered every time Jonathan Sexton was injured. Twenty year-old Carbery stepped in to fill the void on Saturday, with maturity beyond his years on his European debut. He led Leinster in carries (16) and metres made (127) in a brilliant running, attacking performance which drew comparisons to a young Beauden Barrett.
Danny Cipriani
It proved to be an easy run out for Wasps, but even so, Cipriani stepped up to the mark. He marshaled the attack well, providing quick ball as Wasps scored 12 tries. If his performances continue, could Eddie Jones recall the out-half?
Wesley Fofana
Fofana scored a brace against Exeter Chiefs and was a menace throughout as Clermont barely hit third gear to achieve a bonus-point victory inside 43 minutes. He showed power and skill as the French side looked to show last year's group stage exit was just a temporary deviation from their trend of reaching the latter stages of the competition.
