Editor's note: After each weekend's action, senior staff writer Ives Galarcep ranks Major League Soccer's 18 teams in FOX Soccer's Major League Soccer Power Rankings. Here is Ives's order after the eighth weekend of the 2011 Major League Soccer season:

Rank (LW) Team Record (W-L-D) 1 (1). Real Salt Lake 5-1 Last Week: Beat Chivas USA, 1-0, last Saturday.

This Week: vs. Houston on Saturday.

Outlook: Losing Javier Morales is a major blow, but RSL does have depth in midfield to field a quality replacement. RSL faces a reeling Dynamo team coming off a two-loss week, which just might be the right prescription for a team adjusting to life without Morales.

2 (2). New York Red Bulls 4-1-3 Last Week: Tied Los Angeles Galaxy, 1-1, last Saturday.

This Week: vs. Chivas USA on Sunday.

Outlook: Looked very good in the first half vs. LA, but showed vulnerability as well. Teemu Tainio's absence was definitely felt, but the good news was Thierry Henry having another solid game and the back-line holding firm.

3 (4). LA Galaxy 4-2-4 Last Week: Tied New York Red Bulls, 1-1, last Saturday.

This Week: at Philadelphia on Wednesday; vs. Sporting Kansas City on Saturday.

Outlook: Stood tall against New York, with Landon Donovan continue his torrid stretch.

4 (3). Philadelphia Union 4-2-1 Last Week: Lost to Portland Timbers, 1-0, last Friday.

This Week: vs. Los Angeles Galaxy on Wednesday; at FC Dallas on Saturday.

Outlook: The Union's defense held up relatively well considering Danny Califf and Jordan Harvey were out, but the offense continues to be a real concern. Philadelphia just isn't creating enough scoring chances and now a tough week awaits against a pair of tough Western Conference opponents.

5 (9). Portland Timbers 4-3-1 Last Week: Beat Philadelphia, 1-0, on Friday.

This Week: at Seattle Sounders on Saturday.

Outlook: Consecutive shutouts show a Portland defense thriving as a unit and playing well in front of Troy Perkins since Perkins returned to the starting lineup. Diego Charra is settling in well, but the Timbers will need their offense to really start firing in the upcoming derby against arch-rival Seattle.

6 (7). Columbus Crew 3-1-4 Last Week: Tied Seattle Sounders, 1-1, last Saturday.

This Week: at San Jose on Saturday.

Outlook: The Crew increased its unbeaten streak to seven matches, but needed a penalty kick goal to equalize rather than scoring from the run of play. Columbus has benefited from a relatively easy schedule during this stretch, but some very tough matches await in the coming weeks, and the Crew had better start clicking offensively or the unbeaten streak won't be lasting long.

7 (8). Colorado Rapids 4-3-2 Last Week: Beat Houston Dynamo, 2-1, last Wednesday; tied New England, 0-0, last Saturday.

This Week: at D.C. United on Saturday.

Outlook: The Rapids showed a champion's spirit in battling back to beat Houston last week, but lost Omar Cummings to an ankle sprain in the process. Colorado will need Conor Casey to jump right back into the starting lineup.

8 (5). Seattle Sounders 3-3-4 Last Week: Lost to D.C. United, 2-1, last Wednesday; tied Columbus Crew, 1-1, last Saturday.

This Week: vs. Portland on Saturday.

Outlook: The Sounders took just a point from two matches last week, but injury concerns were clearly an issue. What was a bit more of a concern was Seattle's defensive breakdowns vs. D.C. Will Sigi Schmid continue his centerback rotation, or will he settle on two? Whichever two he chooses to face Portland will have a stiff test.

9 (10). FC Dallas 3-3-2 Last Week: Tied D.C. United, 0-0, last Saturday.

This Week: vs. Toronto FC on Wednesday; vs. Philadelphia Union on Saturday.

Outlook: Kevin Hartman bailed Dallas out against D.C., coming up with several key stops to hold off a dangerous D.C. attack. If you're Dallas you have to be concerned about being shutout by a D.C. defense that has been very leaky lately. Not having David Ferreira obviously hurts, but Schellas Hyndman needs other players to step up quickly.

10 (6). Houston Dynamo 3-3-3 Last Week: Lost to Colorado Rapids, 2-1, last Wednesday; Lost to Toronto FC, 2-1, last Saturday.

This Week: at Real Salt Lake on Saturday.

Outlook: What happened to the Dynamo? After an unbeaten April, the Dynamo dropped a pair of losses, including a very difficult defeat against Colorado in a match Houston led later in the second half. Things don't get any easier as a road trip to Real Salt Lake awaits.

11 (11). Chivas USA 2-3-3 Last Week: Lost to Real Salt Lake, 1-0, last Saturday.

This Week: at New York Red Bulls on Sunday.

Outlook: Having to play down two men for more than 45 minutes was too much to ask of any team, but Chivas USA actually did well to limit RSL to just one goal. The toughest part of the loss for Chivas USA was the fact the club has likely lost Marcos Mondaini to a long suspension just as he was finding a rhythm.

12 (15). D.C. United 3-4-2 Last Week: Beat Seattle Sounders, 2-1, last Wednesday; Tied FC Dallas, 0-0, last Saturday.

This Week: vs. Colorado Rapids on Saturday.

Outlook: The story of the week for D.C. was Andy Najar getting back into the starting lineup and really sparking the D.C. offense. Perhaps even more important for D.C. was having the defense put together a pair of steady efforts. Ben Olsen's squad will now face an injury-hit Rapids team without Omar Cummings.

13 (12). Chicago Fire 1-3-4 Last Week: Tied Vancouver Whitecaps, 0-0, last Saturday.

This Week: at Toronto FC on Saturday.

Outlook: The Fire had a golden opportunity to snap its winless streak but wound up having to settle for a home draw. Six matches without a win, and less than entertaining soccer has to have bosses in Chicago wondering how much longer head coach Carlos De Los Cobos will be given to turn things around.

14 (13). New England Revolution 2-3-4 Last Week: Tied Colorado Rapids, 0-0, last Saturday.

This Week: vs. Vancouver Whitecaps on Saturday.

Outlook: Remember when Benny Feilhaber's arrival in New England was going to spark the Revs attack? Two consecutive shutouts later and New England is once again a team struggling to score. Luckily for Steve Nicol's team, the cure for a struggling offense (unless you're Chicago) arrives in the form of the Whitecaps.

15 (17). Toronto FC 2-3-4 Last Week: Beat Houston, 2-1, last Saturday.

This Week: at FC Dallas on Wednesday; vs. Chicago Fire on Saturday.

Outlook: Joao Plata can play. Anybody who watched him at the MLS Combine could see that. Well, except for all the teams that passed on him through multiple rounds at the MLS Draft. TFC put together a solid effort against Houston, but must now show that it can keep from posting yet another embarrassing performance on the road.

16 (14). Sporting Kansas City 1-4-1 Last Week: Bye

This Week: at Los Angeles Galaxy on Saturday.

Outlook: A week off came at good time for a KC squad winless in five. With a chance to get Ryan Smith fully fit, and its rebuilt defense more practice time together, Sporting KC will have no excuse for not coming out strong against the Galaxy this weekend.

17 (16). San Jose Earthquakes 1-4-2 Last Week: Bye

This Week: at Vancouver Whitecaps on Wednesday; vs. Columbus Crew on Saturday.

Outlook: The Earthquakes had a week off to try and figure out what is going on with a defense that was expected to be much tougher this season. The road trip to Vancouver will be key because the Earthquakes will be rested and facing a struggling Whitecaps side. A loss would be brutal and raise serious questions about San Jose's ability to really challenge for a playoff spot.

18 (18). Vancouver Whitecaps 1-4-4 Last Week: Tied Chicago Fire, 0-0, last Saturday.

This Week: vs. San Jose Earthquakes on Wednesday; at New England Revolution on Saturday.

Outlook: Eight games without a win and the Whitecaps are in full expansion funk mode. Considering how well Portland is doing, at what point does head coach Teitur Thordarson start to feel the pressure? If Vancouver doesn't find some points during this two-game week, you can add Thordarson to the hot seat of MLS coaches most likely to be fired.
