Northampton Saints booked a home quarter-final berth in the European Challenge Cup on Thursday with a hard-earned 28-24 win at stricken Montpellier.
The Saints laboured through the second half of a match in which they were clearly superior but were guilty of some lackadaisical handling and rucking at times which nearly let their hosts back into the match.
Ben Foden set up first-half tries for Chris Mayor and Stephen Myler before Sean Lamont's late strike sealed the deal at the Stade Yves du Manoir.
Montpellier took an early lead after Francois Trinh-Duc booted a penalty inside the opening 90 seconds.
Northampton quickly made light of the setback and asserted their superiority.
Foden and Paul Diggin combined to allow Mayor to touch down in the sixth minute.
Myler added the conversion and the hosts' misery increased when flanker Jerome Vallee was shown a yellow card for throwing a punch at Mayor.
The Guinness Premiership outfit doubled their try count in the 21st minute when Foden fed Myler to crash over, but the fly-half missed a conversion and penalty chance to extend the Saints' lead in an ordinary first half.
The Saints failed to wake up after half-time, and Montpellier hit back and took a 17-15 lead when Frikkie Welsh and Louis Picamoles scored in quick succession, with Trinh-Duc landing both conversions.
But Myler edged the visitors back in front with two penalties and Lamont sealed the win with a glorious in and out step, before Grant Rees' late consolation try for the hosts that gave them a bonus point.
