Erik ten Hag was convinced Marcus Rashford would react the right way to his manager's risky decision to bench him following his late arrival to a meeting.
Rashford was left out of Ten Hag's starting line-up for Manchester United's away match with Wolves on December 31 for disciplinary reasons, with it later revealed Rashford had overslept and turned up late to a team meeting.
Ten Hag brought on Rashford with the game goalless at Molineux at half-time, to great effect too as the forward netted the winner.
Rashford then went on to score in the following two games, a 3-0 Premier League victory over Bournemouth and a 3-1 FA Cup success against Everton.
Ten Hag believes dropping Rashford was necessary to set the standard he wants, though he added he was confident the 25-year-old would react in the positive way he has done.
"Maybe it's a risk," Ten Hag told reporters. "But if you want to develop something, if you want to create a winning attitude or winning culture, you have to go this way, in my opinion.
"If you allow them to be undisciplined, if they don't match the standards, and values and rules we set together as a team, that the staff place in the dressing room, then it will come back.

"That will blow up in your face on the pitch, because then also on the pitch, they will not act with discipline, what is necessary to win games, it's about top football. So it's about big responsibilities.
"If it's the right human beings who have the right characters, they will react like this. And so, in relation to Marcus, I was quite convinced."
Rashford's goal against Everton on Friday means he has now scored in five straight games, while he became the first United player to net in seven straight home matches in all competitions since Wayne Rooney in 2012.
Despite Rashford's impressive goalscoring run, United are in the market for another striker, with Anthony Martial in and out of the team with injuries so far this season.
"There is a reason, because he [Martial] can't match in this moment the load for many games," Ten Hag added. "That's why we are looking for another striker.
"It is not about that we don't rely on him [Rashford], but it is a physical load that is not in this moment so high that he can't play every third game of every third day, a game of 90 minutes. I have to manage that together with him."

Although he has been open about United's search for another striker in the January transfer window, Ten Hag is confident in his existing players' ability to put the ball in the net, saying: "Today, Antony scored a goal and we know, Bruno Fernandes is also very capable of scoring a goal.
"Christian Eriksen will create and is capable of scoring. So we have more players who can score goals."
The victory over Everton was United's seventh in a row in all competitions, but Ten Hag is keeping a watchful eye over his players to ensure they do not let complacency creep in.
"You have to be watchful for this," Ten Hag stated. "We have to keep this focus and this concentration we have to work well.
"When we go to games, we have to start with the right attitude. When you don't, the level of the Premier League is that high, you get hammered."
