<p>Arena has historically had the edge in this series in games that really matter, and he&rsquo;s forged a pretty boss-like career of his own. He&rsquo;s won the double twice as well &ndash; with D.C. United in 1997 and then the Galaxy in 2011 &ndash; and like Schmid, he&rsquo;s had arguably his most successful year to date in LA this year. Consider the extenuating circumstances Arena and his group have endured this year &ndash; Omar Gonzalez gone for the World Cup, the Landon Donovan saga, tragedy for defender AJ DeLaGarza &ndash; and the Galaxy&rsquo;s challenge for the Shield is even more impressive. But most important for now? Arena has lost just once in this matchup in the teams&rsquo; past six meetings overall &ndash; the only one came in the 2012 postseason, when the Galaxy won the two-legged Western Conference final series anyway &ndash; and his team holds the psychological edge.</p>

<p>There&rsquo;s a reason the CenturyLink PA staff plays James Brown&rsquo;s &ldquo;The Boss&rdquo; when Sigi Schmid strolls onto the field on game days. Despite being the winningest head coach in MLS history &ndash; his 206 regular-season wins are 30 more than Bruce Arena and 67 more than Dominic Kinnear &ndash; he&rsquo;s been under pressure each of the past two seasons to produce something more than a US Open Cup title in Seattle. He&rsquo;s won doubles before &ndash; with the 2002 Galaxy and the 2008 Columbus Crew &ndash; and he&rsquo;s done a masterful job running this Sounders team, easily the best in his six seasons there. No matter what, however, he&rsquo;s going to have to break that LA hex sooner or later.</p>
