Before the break, Monaco had won 10 of their last 14 Ligue 1 matches - losing just once.
However, Monaco were off the pace at the Stade Louis II and it required Anthony Martial's strike to cancel out Mevlut Erding's opener to ensure a share of the spoils against their fellow UEFA Champions League hopefuls.
Head coach Jardim concedes his team were not at their best and believes the domestic break curtailed his side's momentum.

Monaco will attempt to return to winning ways against Montpellier on Tuesday.
