1. Alex Waller, Northampton Saints
Alex Waller's impact at loosehead continues to soften any impact that Alex Corbisiero's absence has had on the Northampton Saints, the youngster contributing another fine show at Ospreys.
The English visitors ruled the scrum at the Liberty Stadium, Waller also pitching in with a defensively pristine seven tackles.
2. Ross Ford, Edinburgh
It's not often that a front-rower gets his tackling figures into the double figures, but such was the characteristically mobile performance of Edinburgh's Ross Ford against Perpignan, the hooker getting about the pitch well, with 10 in total.
The Scot threw well into the line-out, losing just one in total, pushing his side onto a 27-16 victory that was largely thanks to the pack's fine work.
3. John Afoa, Ulster
Ulster's second-half display at Ravenhill this weekend laid the foundation for a pivotal 27-19 win over Montpellier, with Afoa driving over in the 56th minute.
That vital score was just the tip of the iceberg for the tighthead, however, who carried for an average of almost 10 metres per carry and failed to miss a tackle.
4. Devin Toner, Leinster
Devin Toner isn't often the man in the spotlight for Leinster, despite being their largest star in terms of sheer height.
The Irish international registered a substantial tally of six tackles in the win at Castres and carried less frequently than only two of his fellow scrum teammates.
5. Paul O'Connell, Munster
As ever, Paul O'Connell was the driving force behind a pool-sealing win for Munster in Europe, laying the groundwork for a clinical victory at Kingsholm with his work in the loose, but more importantly in the close game.
