Not since Manchester United destroyed champions Arsenal 4-1 on a glorious opening day of the 1989-90 season has the first match of the campaign brought such a feel-good factor to supporters. After a close season of fantasy summer signings, including a world record £89.3 million move for Juventus' Paul Pogba, Sunday's 3-1 win at Bournemouth produced relief and a sense the reality could be just as good. New manager Jose Mourinho had three different scorers in Juan Mata, Wayne Rooney and Zlatan Ibrahimovic. There were three league debutants, too, in Ibrahimovic, Eric Bailly and Henrikh Mkhitaryan. And although three points were expected, United have been tripped on the opening day before when victories were anticipated, a 3-1 loss at Aston Villa in 1995 probably the most infamous. For most of Sir Alex Ferguson's reign, wins were expected and draws were considered two points dropped. A 1-0 defeat at David Moyes' Everton in 2012 was the start to Ferguson's last season. A year later, Moyes was United manager and won his opening game 4-1 at Swansea. Even then, with Ferguson retired, United fans thought the trophies would keep coming. They didn't, and fans have had to readjust their mindset and lower expectations.
