Gael Kakuta and Simon Banza were the goalscorers for Lens as they recorded a 2-1 win over Charleroi on Thursday.
The match was a tune-up for the Sang et Or who are on a break while the Uefa Nations League is on this week.
They certainly had intentions of winning the friendly with Banza giving them the lead in just the fourth minute before Kakuta doubled it from the penalty spot in the 31st minute.
Charleroi reduced the deficit via forward and Jamaica international Shamar Nicholson in the 54th minute and that was as far as they could go.
