Northampton collected their first Heineken Cup win of the season with a bonus-point 45-0 success over Castres at Franklin's Gardens.
The notable action came in the final quarter of the match as the Saints scored five tries to emphasise their superiority over a very poor French side. Stephen Myler kicked the remaining 20 points for Northampton.
Ben Foden scored two tries and further scores from Vasily Artemyev, Mikey Haywood and Greig Tonks sealed a comfortable victory.
With both teams already seemingly out of the competition, the game lacked real bite as two under-strength sides struggled to put in a performance. There was a muted atmosphere as the crowd accepted there was little resting on the game, with the Saints frustrated by Castres' limited game plan.
The French slowed the game down at every opportunity and were content to allow their outside-half Pierre Bernard to kick away what limited possession they gained. Northampton should have capitalised on their huge share of possession early on, but it was not until late in the game that they were able to do so.
