Jardim was left frustrated by his team's 1-1 home draw with Reims on Friday as Monaco lost further ground on their Ligue 1 rivals.
Monaco - who took the lead through Uwa Echiejile in the 20th minute - wasted a host of chances to extend their advantage and were made to pay with 10 minutes left as Reims levelled proceedings.
In the build-up to the 0-0 draw between the two sides, Jardim urged his side to take their chances and he has sung from a similar hymn sheet once more.
"We have lots of chances in every match... we are not clinical enough," Jardim said.
Nabil Dirar (calf), Dimitar Berbatov (groin) and Borja Lopez (knee) are all set to miss out for Monaco, but Joao Moutinho - who shrugged off a niggling shoulder problem to come on in the second half of Friday's draw - should be involved from the start for the principality club, who have returned to the Champions League after a nine-year absence this campaign.
Benfica have their own injury worries, with Eliseu the latest star sidelined after suffering a foot injury in training last week. Nicolas Gaitan battled through a rib injury to play in Friday's 1-0 Primeira Liga success against Rio Ave - a side Benfica beat in the final of both domestic cups last term.
