After overseeing the Reds' latest Sky Bet Championship loss, assistant coach, Ferran Sibila admitted the performance wasn't at an acceptable level.
The Reds were cast aside by a play-off hunting Forest outfit on Tuesday evening. Already up against it this season in terms of the results, numbers have been lacking in recent weeks too, and it was ever-more evident at the City Ground.
Not only players were missing, but head coach, Poya Asbaghi who was ill.
It was always likely to be a tough challenge, as Ferran admitted, after deputising for his boss. He told us that the first goal changed everything for Barnsley, after what had been an initial bright start by his side.
"It wasn't the best night, that's for sure." The Spaniard accepted.
"We knew that coming here would be a difficult night with the situation that we are in. Playing with players out of position, because of all of the injuries that we have. It's an unfortunate situation to have as many injuries at the same time; there are too much.
"But then still, we prepared 100% and everybody had the belief that we could do something special here. And we started the game in a good way, our pressing was working well, but then we concede the goal."
An uncharacteristic mistake from the skipper, Mads Andersen allowed Keinan Davis to nip in and put the hosts ahead in the East Midlands.
Sibila conceded that it was a pivotal moment in the match, from a reliable performer and that the level of display following it was not what he wanted to see from the Reds, who went on to lose 3-0 and remain rooted to the foot of the Championship table.
"It's a player for us who is always perfect for us, in all that he does, in training and in games, he's our captain and I admire him, and on this occasion he is unfortunate when he tries to pass to Mich (Michał Helik) and he gives it to the striker and he scores.
"This was then a changing point for us in the game.
"And after that moment, our performance was not on the level that we want."
