The bigger picture issue, brought up by others, is that we couldn't seem to unlock a team that put ten behind the ball.
This was a constant problem last season -- our failure being attributed to our lack of width among other things -- but I don't understand why we would play a possession-oriented, dink-around-the-box kind of football in these circumstances.
Knowing exactly what the stadium would be like, the momentum Cardiff would get from their fans from the get-go, the priority perhaps should have been killing off the crowd early by attacking immediately.
Why wouldn't we run out Negredo instead of Aguero -- a guy who loves to shoot anytime, anywhere, and loves to get in the box? Then fire balls into the box like artillery shells? We aren't talking a world-class keeper here. We could get a deflection, or win corners. Firing in from outside the box makes the defense unpack to come to you to defend against the shot, in theory.
It wasn't much of a surprise that our first came on a 25-yard strike. We all laugh how supporters scream "SHOOT!!!" anytime anyone has possession uncontested from 30 yards or less out in front of goal but to me this is what I'd like to see against squads who fill the penalty area. Cardiff certainly executed well, and I realize tactics like this may open us up and perhaps we wanted to protect our second string CBs. But, again, if we can't figure out how to unlock this simple park-the-bus defence, every side poorer on paper than Swans is going to employ it.
