Wayne Rooney's glass was half-full.

"If we beat Arsenal, we're right back in the title race," said the Manchester United striker ahead of Sunday's summit meeting with the Premier League leaders at Old Trafford. With a United victory, the gap between the clubs would be five points. Game on.

What Rooney didn't say is that if United loses it will trail the Gunners by 11 points, effectively four wins. Game over.
