To be fair, Ferguson almost never lost two league games in a row. Maybe a handful of times in his whole career. It was part of the United identity - the ability to bounce back.
That's what is most worrying for the fans.
But I also believe the narrative is shaped by the result. United absolutely dominated the first half, and had Hernandez gambled could have been 2 or 3 up just off of Nani crosses. Then we'd hear that it was an amazing response and Moyes really had them up for it.
Instead, Adnan tries a risky pass (poorly) to Buttner who is overlapping, leaving an entire flank exposed, doesn't track his man who beats only one player, a static Ferdinand, and the narrative becomes how well WBA are playing. That was at 0-0 when United had had virtually every chance of the match.
To me we were exactly the same as last year, but this time RVP didn't produce some magic. Everything else felt the same. We're easy to play against, because you can sit deep and we don't create much except crosses, and our midfield is so slow that they can't protect the back four. At home when we're expected to attack all match, just bide your time waiting for us to get more and more desperate for goals, and then pounce on the break when a pass (like Adnan's against WBA) is done in a risky situation.
I'm shocked we haven't seen Moyes take us back to basics - a well-drilled, defensive solidity, and let the front 4 do the attacking. Instead he gives Ando and the full backs free reign to overlap, and we pay for it.
