1. Matt Mullan, London Wasps
Matt Mullan's fine outing against the Northampton Saints wasn't enough to give his side victory, but the 26-year-old held a fine account of himself up against Salesi Ma'afu and later Tom Mercey.
Wasps were a dominant force in the scrum, losing only one of their own feeds, and Mullan managed to contribute six tackles, not to mention carrying for 23 metres, making him the hosts' third-most effective runner of the ball on the day.
2. Jean Charles Orioli, Toulon
Toulon's 43-10 victory over Montpellier featured a number of blockbuster performances, but a try from Jean Charles Orioli provided the icing on the cake for the hooker, who helped keep his pack rock steady and was a number of forwards who showed great passion in the loose.
3. WP Nel, Edinburgh
Featuring in the team of the week for the second edition in a row, WP Nel was again vital in helping the Scottish giants to another essential win, this time against European titans Leinster.
This was the first game of the campaign in which Edinburgh had succeeded in preventing the opposition from scoring at Murrayfield, helped immensely by the South African's eight tackles and his stability in the scrum, the hosts not losing a single one of their own feeds.
4. Alun Wyn Jones, Ospreys
The battle of the South Wales giants swung back in Ospreys' favour this weekend after Steve Tandy's side managed to hold off a late Cardiff Blues surge in the nation's capital.
And what a surprise that Alun Wyn Jones played a key role in lighting the way to that victory, his 14 tackles being the most of any player on Friday evening and his presence at the line-out as telling as ever.
5. Dean Mumm, Exeter Chiefs
Another lock captain who shone brightly this weekend, Dean Mumm wasn't able to add to a very respectable try tally for the campaign at Sandy Park this weekend, but his influence going forward was nonetheless huge.
Making seven tackles and losing not one of his line-out takes, the Chiefs' pack leader prodded his side to a 16-3 win over Newcastle Falcons, albeit giving away one or two avoidable penalties along the way.
