United play Chelsea at Stamford Bridge on August 14 - Sky permitting.
Macari told manutd.com: "When you see that opening fixture, it's like somebody's said 'right, just to make it interesting it'll be Chelsea v Manchester United.' It's quite interesting that it's popped out, but you have to play them sometime. It doesn't matter if it's the first game, second game, Christmas or at the end of the season. You've got to play Arsenal and Chelsea who are going to be the main challengers again, and it just doesn't matter when you play them.'
