Ole Gunnar Solskjaer has revealed what he told his Manchester United players before preseason commenced.
Solskjaer and his squad will be under intense pressure from United supporters to improve on their sixth-placed finish last season.
The Norwegian says it will take immense discipline and focus to compete with their rivals, and added he was impressed with what he has witnessed so far from his squad.
He told BBC Sport: "We talked about what is required, the standards we have to live up to every single day. The little margins that get you wins. The little tactical tweaks. The first couple of weeks have been encouraging.
"Of course, you always expect people to come in for the first couple of weeks with fresh energy and focus. We have been pushing the limits.
"They have not moaned - maybe that is a bad thing. Maybe we have not worked them enough. But I think we have worked enough so we are fitter and more robust when the season starts. The more sessions you miss out on, the further behind you get."
