Well what happens in the meetings and trainings etc is a complete mystery, but surely you must agree that they will be talking feverently about how they fucked up, who has the potential to fit the system, who they need to bring in, who can be useful as a squad player. This is his season to work things out afterall... no? And regardless of the squad, the manager himself goes through drastic and strategical changes through his career and learning from his mistakes - look at Van Gaals preferred formations during his career.
During that game, at 3-0 down.... how much can you really change?
Last season wouldn't the lack of Poch's impact mean we'd have capitulated and ended up 6-0 down?
We got turned over by Man Utd, lets not forget who they are, and compared to last season where we got turned over a hell of a lot more by more teams, reckon a bit of perspective needs to be reigned in.
And even if we had his perfect squad.... we'll still have a bad day at the office and lose games every now and then.
