Ruben Amorim has two different Manchester United milestones that offer two different conclusions

It's not just US presidents who put stock in their first 100 days in charge. Affecting change in the White House by the time you hit that milestone is considered crucial, but for football managers, that period is seen as being just as important.

So important that one football manager wrote the book on the first 100 days. Literally. Former Shrewsbury Town and Tranmere boss Micky Mellon teamed up with Phil Denton to write The First 100 Days: Lessons in Leadership from the Football Bosses, which included insight from other managers on what they did in that period to get their ideas across.

As Richard Bevan, CEO of the League Managers Association, says in the foreword: "With pressure to win from fans and owners, constant media debate and high levels of turnover, managers are under constant pressure to succeed. The statistics on average tenures of managers across the leagues clearly demonstrate that time is a scarce commodity in the profession. Making a positive important quickly is essential."

Sam Allardyce adds: "I have always thought the first 100 days are absolutely key in creating a winning mentality and culture that can achieve what you need to for the football club."

But the first
