Having conceded 19 goals in the league so far this term, Montanier knows where The Reds must improve but he believes their current problems are down to a lack of concentration rather than tactical issues.
He said: “In the last few matches we’ve had one or two moments where we have lost concentration, either through positioning or marking, and we’ve conceded a goal. We have to correct that quickly because we are losing points in every game.
“We have to be more disciplined and efficient at the back. At the moment we are not taking up good positions and we are opening the door for our opponents. We are working hard to make this right but now we have to go and prove it on the pitch.
“The tough thing in football is to score goals but we have the capacity to do that with the squad we have. Now we have to make sure we improve defensively and stop conceding because you cannot expect to win matches if you keep conceding two or three goals a game.”
Forest now go in search of a morale-boosting home win against a Fulham side who were beaten 4-0 at home by Bristol City on Saturday but Montanier insists Slavisa Jokanovic’s side won’t be travelling to make up the numbers.
He said: “It won’t be an easy game because Fulham lost at home on Saturday so we know they will be motivated to pick up points at The City Ground. But after two consecutive defeats in the league, we need a victory and we need to put in a performance in front of our supporters.
“During October and November the games don’t come as quickly which will give us more time to work on the training ground but we will need points before then. We want to get back to winning games and get back into the top half of the table.
“We didn’t pick up any more injuries in the game on Saturday and hopefully we will welcome back Damien Perquis into the squad for tomorrow. He has recovered well and we’d like to bring him back to provide good competition for places in the back four.
“I hope that Britt Assombalonga will be back after the international break. It’s been very frustrating because it is not a big injury but he is feeling much better and will be training with the group soon. Of course we prefer to have our best players available but football throws these things at you sometimes.”
