Northampton will face a tricky challenge when they return to European competition in the European Challenge Cup in October.
The National Division One champions are grouped with fellow English club club Bristol in Group Two, along with Montpellier and another side recently promoted from their domestic second tier, Toulon.
Toulon, who have signed former All Black Jerry Collins amongst other big names, are back in Top 14 and compete in Europe for the first time since the 1999-2000 season.
Group One sees European Cup semi-finalists London Irish play Connacht, Rovigo and Dax or Albi.
Defeated finalists Worcester Warriors resume against Bourgoin, Petrarca and Romanian club Bucaresti Oaks.
Newcastle Falcons and Brive continue their European Challenge Cup rivalry.
The Falcons are 5-1 ahead in those meetings, including wins on French soil at the home of the 1997 Heineken Cup champions in the last four seasons.
Newcastle and Brive will contest Pool Four along with Overmach Rugby Parma and Cetransa El Salvador.
Pool Five consists of Saracens, Viadana, Bayonne and Stade Montois.
The draw was conducted using the new ERC European Ranking system based on the qualified teams' performances and participation in the Heineken Cup and knock-out stages of the European Challenge Cup over the past four seasons.
