After two action-packed weekends of Six Nations action, we look at five of the players who have stood out from the rest.
1. Peter O'Mahony (Ireland)
The teak-tough Munster captain has been immense over the first two games of the championship. Has been a a terror at the breakdown for both Scotland and Wales. The timing of his disruptions at ruck time and his discipline have been exemplary. Will face a bigger test from the England back-row but nothing fazes this 24-year-old.
2. Billy Vunipola (England)
This guy just keeps getting over the gainline. He has been gathering restarts with assurance and his raw strength and power. The Saracens star has managed to overshadow both Jamie Heaslip and Louis Picamoles who have also started the Six Nations impressively.
3. Wesley Fofana (France)
He may not be exerting the same influence as some of the others shortlisted but has shown himself to be pure box office. Only a handful of players in the Northern Hemisphere could have scored the try he conjured against the Italians. If France are to continue on to a Grand Slam title, the Clermont speed demon will be pivotal.
4. Jonathan Sexton (Ireland)
The Racing Metro flyhalf exploded into life with his blistering break against the Scots that came close to setting up a try for Jamie Heaslip. He saw out the Scottish game comfortably and played the role of the puppet-master perfectly against the Welsh. Arguably his best tactical kicking performance in a green shirt. Place-kicking has also been solid.
5. Courtney Lawes (England)
The most aggressive tackler over the first two games. Throws himself into defensive work with vigour and has been one of England's top carriers. His battle with Paul O'Connell in Twickenham could be epic.
Other players worthy of a mention: Conor Murray (Ireland), Luther Burrell (England), Rob Kearney (Ireland), Louis Picamoles (France), Jamie Healsip (Ireland), dan cole (England), Cian Healy (Ireland), Pascal Pape (France), Michele Campagnaro (Italy)
