Lens have secured their second clean sheet in two games with a convincing 2-0 win over Openda on Sunday afternoon at Stade de France.
The visitors had the first opportunity to score, but Lens' goalkeeper, Mathieu Devecchi, made a fine save to deny them.
However, it was not long before the home side took the lead through a well-worked goal from substitute Yannick Bolasie.
The Belgian striker was brought on as a half-time substitute by coach Christophe Galtier and he delivered immediately.
He received the ball on the edge of the box and unleashed a powerful shot that found the top corner of the net.
The second goal came shortly after the restart when defender Jean-Kévin Augustin headed home from a corner.
It was a solid defensive display from Lens, who kept Openda at bay for much of the game.
The result sees the Ligue 1 side move up to fifth place in the table, just one point behind fourth-placed Monaco.
The win also marks a return to form for Lens, who have struggled for consistency this season.
The team will be hoping to build on this performance as they continue their league campaign against Nantes next week.
