Ligue 1 Review: Lyon stalemate ends goal-shy weekend in France
Lyon were unable to restore their four-point lead at the top of Ligue 1 on Sunday as Hubert Fournier's men were held to a 0-0 draw at Monaco.
Fournier's side saw title rivals Paris Saint-Germain and Marseille pick up wins on Friday and Saturday respectively.
However, Sunday's clash proved a relatively low-key affair - in keeping with the lack of goals across the weekend in the French top flight with just 10 scored in as many games - as the main talking point proved to be a stamp from Monaco defender Wallace on Lyon's Samuel Umtiti.
The second-half incident could earn the Brazilian retrospective punishment - having not been booked - while Lyon look ahead to next Sunday's visit of defending champions and PSG.
Elsewhere, Caen's upturn in form continued with a 1-0 win over Saint-Etienne at Stade Michel d'Ornano with Julien Feret on target for the hosts just before the interval.
The points moved Patrice Garande's men out of the relegation zone, courtesy of a solo run and strike from Feret - the midfielder scoring for the third time in as many games this year.
"We have just won three games in a row. It's not that it does not please me but I will take a little step back from it all. We know that things can quickly change," Garande told his post-match news conference.
"I am, above all, happy with the game and the state of mind my players showed."
With Saint-Etienne suffering a surprise reversal, fellow European hopefuls Bordeaux failed to collect maximum points as they were held to a 1-1 draw by Guingamp.
Maxime Poundje cancelled out Claudio Beauvue's first-half opener after the interval and Bordeaux would perhaps have fancied their chances to seal the win had Jaroslav Plasil not been dismissed 11 minutes from time.
