The winter break must not mask Rennes' Ligue 1 shortcomings, according to coach Philippe Montanier.

The Rennes boss has warned his players not to forget their last league outing, a 2-1 defeat to Sochaux.
Rennes entertain Nice on Saturday in the league's return after the Christmas shutdown, with Montanier's side gunning to arrest a three-game league losing streak.
Rennes started 2014 with a 1-1 draw against Valenciennes in the Coupe de France, but Montanier admits that cannot hide their need for league progress.
"We must remember the details of this last league match," Montanier told Rennes' official club website.
"We must not repeat this kind of performance."
Nice have ended a seven-defeat slump in fine style with four straight victories, leaving Montanier cautious of the challenge ahead this weekend.
"Their poor run of results was due to several reasons, including the large number of injuries," he said.
"But they still played well and I am not surprised their luck has changed. They finished fourth last season and little has changed at the club this year."
Montanier admitted he will not look to take Nice on at their own game of possession football.
"We will adapt, against St Etienne this was also the case and we won," he said, reflecting on Rennes' last league victory, 3-1 on December 4.
"We do not want to make a game of it that way.
"The pressure will go right to the end of the season and each match will be important."
Nice boss Claude Puel can include Argentinian Dario Cvitanich in his squad for the Rennes trip, the striker back in action after a trip home.
Mahamane Traore has not found fitness in time, but Puel admitted he is happy with the strength of his squad.
"I am satisfied with my team," Puel told Nice Matin, "especially if we maintain the numbers fit we have now.
"We have a quality squad with two players for each position.
"If there are one or two adjustments that are not planned, that's what can happen in a transfer window, but there are no big plans."
