Bayonne won 22-19 at Rodney Parade in a Round 2 thriller after back row forward Tom Brown scored an early try for the Dragons with full back Tom Prydie contributing the rest of the points with the conversion and four penalty goals.
If Mike Phillips' Bayonne can make home advantage count then they will remind Wasps they cannot afford to take anything for granted while the Dragons will then welcome Wasps to Rodney Parade in Round 6 and have a say in the fates of both Bayonne and Wasps.
