If you are a fan of Manchester United, you will know the importance of this game.
It is just a Community Shield. The opponent is Wigan. The game probably don't have much bearing on how the team will perform, but this will be the first game that United will be playing at the start of the season under a new manager, after 26 years of under the leadership of Sir Alex Ferguson.
The Community Shield, a semi-competitive curtain-raiser, rarely means as much as Sunday's fixture might do. Moyes has a chance to either win his first silverware or suffer the first onslaught of failing to match the achievements of his predecessor. Still, at least he might be able to talk about football rather than faltering transfer business.
For David Moyes, anything less than a victory and by some margin too, will be a hugely damaging reverse. And with style too. United's attacking traditions need to be in evidence. Wigan are a Championship club, the humiliation of losing to them is too dark to contemplate. Moyes has looked pained of late, and pre-season has been something of a pain to him too. The real business starts at Swansea next Saturday, but a win at Wembley will be a definite perk to spirits that have taken something of a jolt.
So, what will be the formation and playing style under Moyes look like? You won't have to wait long to know...
