I wrote earlier about some luck that went our way earlier in the season.
Now, the ball is bouncing the other way.
Think of it this way: Just a few inches: In the Liverpool match, Aguero puts the ball slightly out of the reach of Silva, who barely gets a toe on it and his attempt goes wide by a few inches. Two minutes later, against the run of play Kompany muffs a clearance and the Liverpool midfielder puts in a perfect shot.
After the Sunderland keeper muffs a shot right at him from Nasri, in extra time Nasri has a wide open shot from within the box go over by a few inches.
If Silva was able to get more foot on the ball and Nasri a little less, we'd be crowing about how we were going to be top of the table. Instead, we're praying for some luck. All because of a few inches.
