Iron boss Mark Robins was frustrated with his side’s performance at Colchester and also the goals conceded in their 2-2 draw.
Robins was pleased that his side were able to get another point, which helps his side further away from the relegation zone, but demanded an improvement from his players.
The manager told The Iron Player: “It's another point gained as we go five points clear of those below, but I'm really not happy still. The job's there and it has to be put to bed.
“It's another game where we have come away unbeaten, but it's still not good enough. We are better than that and they've got to understand that and take the belief and take it on board.
“If we win on Tuesday it does see us safe, but it's down to three games and we feel it should have been put to bed a long time ago. It hasn't been though and it's not been good enough.”
The Iron boss hopes that his side can cut out the mistakes that he feels is costing his side goals and also points, and was annoyed at the goals against Colchester.
Robins said: “The only change I made on Saturday was bringing in another midfield player in for a forward player because we knew the conditions were going to be as they were.
“They're not a bad side, but having said that we coasted through the game and thought we'd done enough. We switched off for the two goals and were trailing with a few minutes left.
“We've managed to claw our way back into it at the end though. They were poor goals to concede. We shot ourselves in the foot, and I say it every week.
“We've given a goal away from a corner and that sort of thing has to stop. The players have to grow up and take responsibility because that is totally unacceptable. We have to avoid being dictated by our opponent.”
The Iron remain 17th, but are now five points ahead of the bottom four, meaning that a win should guarantee League One football at Glanford Park next season.
Robins is expecting a tough test from Bradford on Tuesday evening, but hoping to put on a performance to remember for the Iron fans.
He said: “They're a good side and are another side that took a heavy beating on Tuesday, but we know what their qualities are and that they're a decent team.
“We are too and we've got to come out of this. It's a point nearer to our total and we have to put a decent performance on for our supporters.
“The good thing is we've got two home games to look forward to playing in front of our fans. We've got to better than we have been though.”
