The point saw the former French champions move up to ninth in the league table with 49 points from 35 matches.
"It's a point won because we had a reshuffled side and were playing against a side pushing for Europe," he told reporters. "The team was very courageous, but we lacked a little technical precision.
"When we won the ball back we weren't able to do much with it as there were too many mistakes. That's the regret I have.
"Up front, we didn't show much, but we did what we had to do at the back. Cedric Carrasso made some top-class stops. That's not enough. We have to work more going forward."
Saint-Etienne are fourth in the standings.
