Manchester United interim manager Ralf Rangnick reportedly waited until Monday to inform the players of his tactics for the team's game against Liverpool on Tuesday.
The Red Devils were comprehensively beaten 4-0 at Anfield. The result leaves United sixth in the Premier League, three points behind Tottenham in fourth having played a game more. Arsenal are also in the hunt for Champions League football, sitting in fifth.
It's not unusual for managers to hold back the starting line-up until the day before a game, yet they usually reveal their tactics much earlier. This allows players to prepare for the task ahead by practising shape and style. They also have time to analyse their opponents.
