it did really have the feel that they hadn't really experienced putting their style on the line against a team of our calibre who could really hurt them, much like Chelsea turning up to us seemingly invicible and we showed that they are actually quite ordinary. I'm not saying Monaco are ordinary, but Jardim has a lot of work to do because his team just seemed at a loss at times of how to handle us walking through them, they just weren't disciplined enough, actually were guilty of being like us and leaving the back door open all the time which punishes us so often in the league.
Perhaps the beginning of your post, if i read you correctly, provides the answer to their problems tonight. You can watch whichever 2 or 3 of their games this season (you won't need more unless you want to study them thoroughly) and you'll understand what I mean (with the exception, of course, to their heavy defeat at Nice which was an one off; there's an explanation for that but I won't get into it at the moment, we're already off topic). It's not about lack of discipline, clearly it isn't. Jardim trusts his team, was confident enough to field 2 SC at the Etihad (the second one not even being Germain...). He trusted in his attacking game, believed his team would score -as it happened. But he also trusted in his defensive structure. He knew Yaya would basically stay deep, so thought our numerical advantage in midfield wouldn't be a big deal. As far as I am concerned, he underestimated the quality of our attacking game, the kind of situations we can produce in small spaces which theoretically seem covered. It could have been even worse provided we had the sharpness to feed David / Kevin in advanced areas more often from behind, every time we did that a combination was ready to unfold. Another thing he didn't expect was Aguero's game tonight, if you ask me. Moving deep, avoiding his markers, Sergio became an excellent reference upfront, setting up runners from behind, occasionally first touch, occasionally in a totally unpredictable manner. Monaco had no answer to that. When you release a player like David running at you facing the net, with players like Raheem / Leroy moving in space, either cutting in or staying more wide, a through ball will most certainly occur...
Plus, as I said, they probably felt it was over after 61', like we wouldn't have the mental strength to respond again...
Anyway, I'm not going to say he'll be regretting his initial game plan, but I bet he will watch again and again and again the 2nd half so as to explain his team's behaviour. To use your words, I wouldn't be surprised if he would feel "guilty" for not swiching to a 3-man midfield in the process, for example. So as to control the game more effectively...
