The Reds' Head Coach is looking for another intense performance from his young side when Barnsley take on Swansea in Wales this Saturday.
With the Reds still without Jordan Williams who had another scan this week, which will delay his return to training, and no Callum Styles this weekend as he serves a one-match suspension, the Reds' boss says he's looking forward to others taking their own chance when Barnsley face the Swans on Saturday.
"It is an opportunity for others in the squad." Stated Ismaël.
"For Stylesy, this is also maybe a good thing as he gets to breathe, he can rest ahead of more fixtures without risk of an injury.
"I always tell the lads they must be patient, but ready and waiting for their chance.
"We have a good team spirit and in this position we have the possibility to make a change, and now they must take their chance."
Saturday's hosts sit fourth in the table, and although they lost their last game in midweek - 2-0 at Derby County - they have been in impressive form this season.
Indeed, they've lost just one game at the Liberty Stadium.
"Any game is a big test for us." Admitted Valérien.
"But Swansea is one of the top sides. They are a possession-based team, and so we need another forceful performance.
"We need a high-intensity game from the lads, we need to be ready to suffer. Because there will be a lot of running, we need to make things tight and create our transition game.
"When we get chances in the box, we need to be clinical again.
"We have prepared for this, and we want to get another three points."
With the Reds on a three-match winning run, there have been some suggestions in the media that Barnsley could be looking capable of pushing for the playoffs.
But the gaffer wasn't interested in any talk about his side's prospects for the season, instead reminding people that we take each game as it comes.
"We aren't looking at anything beyond the game on Saturday. That is our sole focus as a club and as a team.
"I keep saying we take games one by one, and I will continue to say that.
"Tomorrow is the next chance for a win. That's our aim, our focus."
