London Wasps and Bayonne will fight it out to see who qualifies for the Amlin Challenge Cup quarter-finals when they two sides meet in their back-to-back games in Pool 3.
Wasps, who won this tournament in 2003, recorded an emphatic 59-12 victory over Rugby Moliano in Italy to put them top of the table and ahead of Bayonne by a single point.
The English premiership side, with international prospect Christian Wade in blistering form, have crossed for 13 tries and secured two bonus point wins already in their opening two Pool games.
Bayonne had to battle hard to secure their 22-19 win over the Newport Gwent Dragons at Rodney Parade but the England versus France clash holds they key to qualification.
"It will be interesting to see who comes out on top of the back-to-back games between Bayonne and London Wasps in December," said Dragons coach Darren Edwards.
