Troyes coach Jean-Marc Furlan has warned his players to expect an even tougher Ligue 1 encounter with Rennes tomorrow when the teams go head to head for the second time in four days.
Furlan's side head into the weekend second-bottom of the standings and on the back of a 2-1 defeat against Frederic Antonetti's team in Thursday night's Coupe de la Ligue quarter-final at the Stade de la Route de Lorient.
Promoted Troyes have the chance to exact swift revenge at the Stade de l'Aube tomorrow, but Furlan does not anticipate an easy ride against eighth-placed Rennes.
``We were very disappointed and frustrated over our performance against a great team (on Thursday),'' he said.
``Thursday's game could have served us well for Sunday if we had qualified. It was Rennes' obligation to qualify. On Sunday they will be liberated. It will be much more difficult.
``Since September we have not been successful, defensively or in attack. So it's very hard, but the spirit among the players - most of whom are just discovering Ligue 1 - pleases me.
``We leave the competition with our heads held high.''
A late winner from Romain Alessandrini earned Rennes a place in the last four of the cup after 17-year-old Corentin Jean had marked his senior debut for Troyes by cancelling out Jonathan Pitroipa's early opener.
Antonetti was pleased with his side's progress, but acknowledged improvements need to be made.
``We got the job done,'' he said. ``It became a difficult match after we began so well.
``It was a cup game with many opportunities. In the second half we were more solid and present, and the guys went on to snatch victory.
``We must know how to win with guts - this is a quality that we have not often shown in the past. There are things to adjust, of course. We could have lost - there was no margin.
``We could have widened the gap but I don't understand why we lost our shape instead. We took our foot off the gas and left ourselves vulnerable against a side who were pushing hard.''
