Lorient are the leaders in the league, but they still have to fight for the top spot, so they have great motivation.
Besides, Lorient got 2 successive wins recently, and played well at home, winning 8 of 11 home games.
On the other hand, Le Mans were winless in their last 4 matches, with poor morale and form.
So Lorient should not be overestimated.
The favorites should be supported to win.
