In the match between Chateauroux and Niort, the latter, who had an impressive game against Nancy, has the advantage. Chateauroux has shown underwhelming results in their recent matches, with 4 losses in their last 5 games, and they are currently in 18th place in the league table. On the other hand, Niort is in 2nd place and has a much more consistent form, with 11 wins in 20 matches. The team also has a better goal difference, giving them an advantage in this matchup. Based on these factors, my prediction is that Niort will win this game.
