Manchester United manager, Erik ten Hag, revealed how he had to revolutionize his players' eating, sleeping, and recovery habits when he took charge.

He issued a stark warning to his players ahead of the upcoming season, emphasizing that they cannot lead a luxurious lifestyle if they want to endure the rigorous demands of elite football.

In an interview with the Daily Mail, Ten Hag said, "For all the players,

you have to live the right life. Professional football is tough, so in general, our players can't match the sensational life playing top football."

"Top football is tough nowadays: 60 games a year in club football, 10 international games.

"So 70 games means that every third or fourth day you have to match the highest physical levels. When you're not living the right life, you get killed.

"What is important? Sleep, recovery, nutrition. Three key areas and when you don't do this right, you have a problem. You can't perform." So when you ask me about [Marcus] Rashford, the same counts for Raphael Varane and every player. You will not reach the levels when you don't do the things right."

The Dutchman explained that he was surprised at the squad's customs when he took over as United manager last year and had to overhaul their habits. He added: "So I think in general when I came in at Man United, the standards were not righ't.

That's true. I demand the highest standards in sleep, recovery and nutrition because that makes the difference if you can perform every third or fourth day. We had to improve.

"That is the demand for every top football player, so at Man United we are demanding the highest standards."
