Many now believe that a team must be full of people, that everyone is a close friend, and that once there is a quarrel or two, it will be titled "infighting". However, in fact, even close friends and relatives are inevitably quarrelsome, let alone a group of flesh-and-blood young people. British media revealed that in the era of Fu Jue's coaching, the players in the Manchester United squad were definitely not harmonious, and they even quarreled openly on the training ground, but witnessing all this, the old lord was smiling.

Former Manchester United sports psychologist Bill Beswick revealed that on his first day of work, he saw an argument on the training ground, but Furjue did not laugh back and told him that this was the driving force behind United's success.
Beswick recalls: "My first day I went to Manchester United and saw the team in 8-on-8 possession training. Roy Keane, as we all know, he's not just an athlete, he's a fighter, he's not just competitive, he's more combative, he has the spirit of a fighter, and his team was in possession at the time. Dennis Elvin got the ball, he looked up, but he was surrounded by opponents and would most likely lose the ball."
"At this point, Keane made a wonderful run and shouted 'Dennis' to signal his teammates to pass the ball. Dennis didn't see him or hear his shouts, he didn't react, and as a result the ball was snatched. Keane ran 40 meters to berate his teammates: "Raise your head and kick the ball!" I was shocked to see it."
But what surprised Beswick the most was not the argument between the two Irish and Manchester United teammates on the pitch, but the reaction of The Lord. You might think that Lord Fury would worry about his teammates turning against him, but the old lord had a smile on his face. Beswick added: "I was sitting next to Manchester United manager Alex Ferguson and he saw my surprised expression and said to me: 'Boy, now you know why we can win on Saturday, we win on Saturday because there is such a spirit in training every day.' 」
In United's 1999 Treble squad, Keane and goalkeeper Peter Schmeichel had a big fight, while Andy Kerr and Sheringham didn't speak to each other off and off the pitch for more than a decade, but that didn't stop them from fighting side by side on the pitch and fighting for the title. Warriors who fight side by side do not necessarily need to be friends, but can still live and die together for the same faith. Today's Manchester United players Mason Greenwood, Marcus Rashford and others need to learn from the professionalism of their predecessors in the game.
In his autobiography, Schmeichel said that while Wenger may be better than Verde in terms of tactical ability, United can make up for it with fighting spirit.
"I don't need to say more, it's no secret that Furthy didn't like Wenger back then." Schmeichel said, "I think he's also worried that people think Wenger is a better coach than him. Wenger is tactically superior, he comes from France, where football theory is more sophisticated, so when we face Arsenal, Fleborg is always more intense. We know how good Arsenal are and they know we're strong. Manchester United against Arsenal may never be as tit-for-tat as Liverpool, but at a higher level, because it is not an exaggeration, and the winning side will win the title. If we had lost the 1999 FA Cup semi-final, we might not have been able to achieve the Treble, but after playing one less person to win, we became unstoppable."
