It's down to the wire now for the five contenders who have been shortlisted for the ultimate individual accolade in northern hemisphere rugby, ERC European Player of the Year 2013.
Winger John Rudd's early try put the visitors on the front foot, and three penalty goals from New Zealand fullback Bruce Reihana helped the Saints to a 14-7 lead at halftime, despite the loss of England hooker Steve Thompson to the sin-bin.
Reihana banged over a fourth penalty goal from long range to settle his side's nerves in the 48th minute, and things looked good for the English club when Narbonne's inspirational backrower Christian Labit was sent to the sin-bin.
Test winger Ben Cohen scored in the corner after some good work from Jon Clarke, and Labit's second yellow card and one to former Test prop and Narbonne try-scorer Franck Tournaire ensured Saints returned home with the points.
With Bristol expected to despatch Italian minnows Viadana on Sunday, Pool 1 should be decided on January 14, when the Saints host their English rivals at Franklin Gardens.
In Pool 3 tonight, Bayonne bagged a predictable 45-6 victory over Romanian club Bucuresti, but must beat Gloucester at Kingsholm in the final round to have any chance of topping the pool.
Winger Vincent Noutary and hooker Christophe Laurent both scored try doubles in the one-sided match in Bayonne.
