I didn't use the words 'shocking defending' anywhere in any post of mine as 'shocking' in that sense is not in my vocabulary, so I'm not sure why you slid little quotations around it, as if I said that. He made the wrong decision there, no matter how you look at it. Imagine if he'd have gone for goal instead. Then it'd have been "He didn't imagine Silva would try such a cheeky shot". That situation desperately called for a tackle and I threw my remote when Masche failed to even attempt it.
If it weren't for Pique saving Masche's ass time, after time, after time we'd have gone down by multiple goals. Yes, Mascherano made that one block, but to call it the best chance City had is just playing up the quality of the shot. Pique's last man tackles on Aguero were far more crucial as missing those (The way Mascherano missed his) would have resulted in Aguero going one on one with our keeper who can't dream of getting more than 3 games in any given month not called January.
When you play defense no matter how well you play if you fuck up and cost us points all of that goes away. You wouldn't be able to say Pique had a good game if he made 15 last man tackles but made two huge errors that costed us the match, now would you?
No, Pique did. He had several of them, actually. Whether or not Masche saved a goal is up in the air as well. We have a goalkeeper who also needs to be beaten, after all, and it's not like his positioning was too poor to save it. Pique tackling Aguero and Dzeko as the last man were far more crucial.
