Well now. That was pleasing.
You really can't pick apart a 4-0 Champions League win, especially when you throw in the fact it was FC Dallas' first real game of the year. The Panamanian side is not the same group, either in players or form, that tore through their CCL group play, but they are into their season and, in theory, a level of game-shape you shouldn't expect from the local guys.
Get used to it. FC Dallas already had the hype machine at Mach 1, but now, after whipping up a CCL quarterfinal result unlike anything a MLS team has previously managed - MLS just went on high alert.
