After an underwhelming second season in charge of Man United, Erik ten Hag is under pressure. The future of the Dutch coach is uncertain, with the club's new minority owner Sir Jim Ratcliffe unconvinced that he is the man to return United to the top of English football. That uncertainty has resulted in several top managers being linked with the Old Trafford hot set, including Zinedine Zidane. Zidane was back in Madrid this weekend for a legends match against Porto, ahead of which he spoke about why he resigned from his position almost three years ago. "I know football and I know the demands of a club like Madrid," Zidane said, "I know that when you don't win you have to leave, but here a very important thing has been forgotten - everything that I have built on a day-to-day basis has been forgotten, what I have contributed in the relationship with the players, with the one hundred and fifty people who work with and around the team." The former France star highlighted three things that must be present for a club to be consistently great He said "I am a born winner and I was here to win trophies, but beyond this are human beings, emotions, life. "And I have the feeling that these things have not been valued, that it has not been understood that this is also how the dynamics of a great club are maintained. "In some ways, I have even been reproached for it. Today the life of a coach on the bench of a great club is two seasons, not much more. Suggesting he wouldn't take the United job unless those things were assured. For it to last longer, human relationships are essential, they are more important than money, more important than fame, more important than everything."
