I don't think we are at all. I think we've generally been poor defensively. I refuse to believe that these errors, are completely unrelated to the change in manager. When players made mistakes before others were there to mop them up. The lower line meant there wasn't as much ground between keeper and central defence. The full-backs staying back more often meant there was usually more players on hand to clean up as well. If Clichy had been available would Nastasic have nodded it back to him? Most likely, and was there any need for Clichy to go forward considering how abysmal his attacking record is? Most likely not. Barry also played further back and by far the best aspect of his game was his ability to read the game and mop up the mistakes. I don't think any of this is an accident. Pellegrini was brought in to be more attacking, and he has been. As a a result we've been more exposed and conceded more. It is not in any way unfathomable. It was in fact predictable. Most of us predicted it, you included:
Unfortunately it is currently affecting results, if/when the time comes when it isn't costing us points, I will shut up about our defence. Until then, it will cost us trophies and that's the name of the game.
