Northampton Town manager Keith Curle says he challenged his players to be aggressive both in and out of possession in the 3-0 win at Grimsby Town on Saturday.
"It was a really good performance on Saturday," he said.
"We showed Grimsby the respect their recent good form deserved but from that point it was all about us.
"We nullified their rythym and our work rate helped disrupt them.
"We challenged the players to be aggressive, both in and out of possession and they were that.
"I made some changes to the side on Saturday and those players who were left out were disappointed and frustrated. That's what I want and what I expect. I don't want players who are happy sitting out and we have good players who didn't even make the eighteen on Saturday. We are a squad, we work together but we also challenge and compete with each other and drive each other on and that is healthy.
"If anyone who was left out and they feel they don't know why, my door is open for them to come and talk to me. Sometimes we make changes to the team to challenge those players who have been left out to come back stronger, sometimes it is tactical because we think we can make the team stronger to counteract certain threats from an opposition or to pose different threats to an opposition, based on what our homework tells us.
"Those who were left out on Saturday have done very well for the club and will continue to do so because of their attitude, their professionalism and their work ethic, I am sure we will need them at some stage and I know they will be ready."
