A miserable day for Rennes ended with the side having two men sent off.
Rennes did not enjoy their visit to Valenciennes in Ligue 1 after a 4-1 defeat and two players seeing red.
The visitors went one up when Jonathan Pitroipa scored on 30 minutes, shortly before Maor Melikson levelled things.
In the second half Dimitri Foulquier John Boye were sent off in the space of six minutes and the home side took advantage.
Lindsay Rose, Kenny Lala and Nicolas Penneteau all scored for the hosts to confound a torrid day for Rennes.
