Nigel Clough is urging his players to transfer their work on the training ground into game situations.
United head to play Peterborough United at London Road on Tuesday and Clough knows performances must improve after an indifferent display against Coventry City at the weekend.
Clough commented: "We are still striving for that balance within the team; we will make minor changes until we feel we have got it right, although we need to pick points up during the process.
"We played well for 30 minutes at Coventry, but we were poor after that. We have got to try and control the game for a longer period of time and capitalise on the chances we create, because we should have scored more goals in the first two league matches.
"We are only talking small margins, but things are going against us at the moment and it is down to us to change things."
Looking ahead to the challenge of facing Darren Ferguson's Posh, the Gaffer remarked:
"Peterborough have probably slipped under the radar this summer and people perhaps thought they would struggle without Assombalonga, but they do seem to have the knack of nurturing striking talent from non-league and they are coping well.
"Everyone talks about ourselves, Bristol City and Preston, but in previous season Peterborough have attracted a lot of attention and they should do well again this season, they will certainly expect to be there or thereabouts."
