Manchester City boss Mark Hughes admits he allowed his players to get away with things last season that he has since clamped down on.
Hughes says there is now a greater level of discipline within the City squad after stating it would have been the wrong time to take a hard-line stance during his first year in charge.
He said: "Last year there were occasions when I compromised my own standards and values and that didn't sit comfortably with me so I knew it wouldn't continue.
"Little details involving disciplinary indiscretions become big problems if you don't address them, but in the short term, I couldn't do anything about it. It was the wrong time.
"The benefit of addressing those little details at that time would have caused problems. Instead of solving problems, they would have created bigger problems. That was why at times I let things go. Not to my comfort, I have to say.
"But I knew there would be a time last summer where any of those issues created by certain people would be addressed because those people would leave.
"Managing a football club is about building a culture. I would suggest a lot of other managers don't get involved in trying to build a mentality, but I don't think you can be successful without it.
"It is about trying to get a work ethic and a way of thinking that enables you to be successful as a group. If you have too many pulling in the wrong direction, you have to cut them off.
"My values won't be compromised in the future because we are in a different place now."
