9:53 PM ET: Welcome back to our live coverage of the MLS Cup Playoffs!
9:14 PM ET: How do you see our match playing out tonight? Leave us your comments in that section below or tweet us at VAVEL_MLS.
9:12 PM ET: Three of their four home losses though came to club’s who made the postseason, only one of them is still active in the postseason though (LA Galaxy).
9:10 PM ET: Seattle comes into the game with an excellent home record having won 12 of 17 matches at CenturyLink Field with a goal differential of plus-15. They have won four of their last five at home coming into tonight’s match.
9:08 PM ET: They had ten road matches with clubs who made the postseason in 2014 finishing with a record of zero wins, four draws, and six losses. They were outscored 17-8 in those matches.
9:06 PM ET: FC Dallas does not have a good road record this season having won only four of 17 matches away from Toyota Stadium. They added five draws and have a goal differential of minus-1. The note to make about this record though is that all of their wins came against teams who did not make the postseason.
9:04 PM ET: With those changes that would likely mean that Pappa, Cooper and Barrett would be the first choices off the bench if a goal is needed late in the match. Michael Azira and Djimi Traore would likely be the first choices off the bench if the sub is more defensive minded. Jalil Anibaba will probably be the odd man out on the bench.
9:02 PM ET: If Pineda does indeed start, that would likely relegate Marco Pappa to the bench, despite his great form as of late, and push Brad Evans out to the right side of the midfield.
9:00 PM ET: On the Seattle front, Gonzalo Pineda may be in line for a return to the starting eleven after practicing all week according to manager Sigi Schmid. The same might not be true about preferred substitute Andy Rose who has not appeared since October 10 in a 1-0 loss to the Vancouver Whitecaps.
8:58 PM ET: When all is said and done look for Andres Escobar to be the odd man out but if Dallas is trailing around the 60th minute, look for him to be brought on as a change of pace player possibly for Akindele with Diaz switching to the left side of the midfield.
8:56 PM ET: Akindele brings a little bit more size to the attack at 6-foot-1 but Escobar has some blazing speed on the right side. He frequently left Leo Gonzalez in his dust in the first leg.
8:54 PM ET: The addition of Diaz to the lineup will mean that one of the midfield starters from the first leg will sit out. The question becomes then is it Andres Escobar or Tesho Akindele?
8:52 PM ET: FC Dallas will get a huge boost tonight with the return of playmaking midfielder Mauro Diaz. Diaz missed the first leg at home last week after picking up a red card in the wild-card game against the Vancouver Whitecaps.
8:50 PM ET: A draw where both clubs score two or more goals: FC Dallas advances to the Western Conference Final.
8:48 PM ET: A 1-1 draw: The match will go to extra time and possibly penalty kicks.
8:46 PM ET: A 0-0 draw: Seattle advances to the Western Conference Finals
8:44 PM ET: Seattle or Dallas win: That club advances to the Western Conference Finals.
8:42 PM ET: The advancement scenarios are as follows for tonight’s match:
8:40 PM ET: Our aggregate score coming into the second leg tonight is 1-1. Seattle with the crucial away goal which could loom large.
8:38 PM ET: The lone win for FC Dallas came on May 25, 2011 when Brek Shea’s 18th minute goal was enough to send the 36,026 fans who showed up home disappointed. That loss ended a short three-match unbeaten streak for Seattle, after that match though they would go on a nine-game unbeaten streak that included win at Real Salt Lake, LA Galaxy and the Portland Timbers.
8:36 PM ET: Seattle has won five of the previous seven matches at CenturyLink Field against FC Dallas including the last four. In those four, they have outscored FC Dallas 12-4.
8:34 PM ET: This will be the eighth meeting all-time between the two clubs at CenturyLink Field. History is very much on the side of Seattle.
8:32 PM ET: The team that emerges from this series will take on the Los Angeles Galaxy who were very impressive in beating Real Salt Lake 5-0 last night at the StubHub Center after a 0-0 draw in the first leg.
8:30 PM ET: Good evening and welcome to VAVEL USA’s live coverage of the 2014 MLS Cup Playoffs. Tonight our match is the final match of the Conference Semi-Final Round between the top-seeded Seattle Sounders FC and the fourth-seeded FC Dallas. My name is Matthew Evans and I will be your host this evening for this huge playoff match.
