Peterborough boss Graham Westley says his team need to look at how they recover from weekend fixtures if they are to improve their midweek record.
Posh's 3-2 defeat by in-form Bury meant they have lost 12 of their last 15 Tuesday night games.
"We need to learn to recover because I didn't feel our energy levels were where they were at the weekend," Westley told BBC Radio Cambridgeshire.
"There's a more aggressive attitude we can adopt to have the belief to win."

|Since the beginning of last season, Peterborough United have won just two Tuesday night games - one against Crawley Town in the League Cup in August and one away at Sheffield United in March|
Despite their poor form this season, Westley believes he can implement changes that will have a positive effect on the team's fortunes.
"There's lots of areas where we can get better and I can make them much better just by introducing some simple procedures, which is where encouragement comes from," he added.
"I want us on top of games, playing on the front foot from the off. I don't want us reacting to adversity. We need to be much more positive with our football."
Peterborough are 15th in the League One table following the result against Bury, and have lost half of their 10 games so far this season.
