Manchester United star Bruno Fernandes has praised manager Erik ten Hag for imposing order on players since arriving at Old Trafford last summer.
Ten Hag took over as United manager in July, after a disappointing Reds campaign saw the Reds finish 6th in the Premier League, 13 points behind the top 4.
Fernandes admitted they were initially unsure of how tough the former Ajax coach was, but it soon became clear that he would demand exemplary behaviour on and off the pitch to change the team's fortunes.
Fernandes said in an interview with former United star Rio Ferdinand: "He arrived first and we went on tour and the training sessions that we had, and he started demanding. You'll do it or get out. You're not going to play."
Cristiano Ronaldo
"Everyone was having a little bit similar feelings at first. Will he do it or not? If the big player doesn't do what he wants, will he be punished or not? He has done it several times, with Cristiano (Ronaldo), with Jadon (Sancho), with Marcus (Rashford)."
Ten Hag has already dealt with a number of high-profile issues in his first six months at Old Trafford, and used to leave Ronaldo out of the starting line-up, and left him out of his squad after the Portuguese star reacted angrily when asked to come on as a late substitute against Tottenham.
But it was the way Ten Hag dealt with Marcus Rashford in late December that really impressed Fernandez.
After returning from the World Cup, Rashford scored in back-to-back games against Burnley and Nottingham Forest, but missed United's New Year's Eve trip to Wolves, due to late attendance at the team meeting.
Rashford's mistake
Fernandes believes it would have been easy for Ten Hag to overlook Rashford's mistake, but the Dutchman decided to exclude the England international from the starting line-up.
Fernandes claimed Rashford understood Ten Hag's position, explaining: "Marcus was probably at his best against Wolves, he did something wrong and the manager pulled him out.
"At first glance we thought he was our main star, we need him, but at the second minute I was sitting with David (De Gea) and I said, 'It has to be like this, because if not, the younger ones will think. If he doesn't do anything for them, he won't make decisions about me either."
"Rashford demanded that he be consistent in everything, not only in games, goals and performances but also off the pitch. Marcus at the beginning was uncomfortable because he wanted to play, he didn't do anything wrong, he accepted it, he came on as a substitute and scored and we won, and in the end he and the coach laugh."
"Sometimes you have to set the rules in your house or they will overtake you and become the owners of the house," he concluded.
