Los Angeles remains atop the Rankings this week after signing Robbie Keane prior to the close of the summer transfer window.

1. Los Angeles – Robbie Keane's arrival makes the Galaxy the prohibitive favorites to win MLS Cup. Can Bruce Arena's side handle that burden? (1)

2. FC Dallas – Is there a better team from the run of play at the moment? (3)

3. Seattle – Sigi Schmid may eventually lament Sounders FC's inability to sign another forward during the summer transfer window. (2)

4. Real Salt Lake – Toronto FC continued its hex over RSL at BMO Field over the weekend: the Claret-and-Cobalt hasn't scored there in five regular season visits. (4)

5. Columbus – “It's really good,” Crew defender Julius James said about his rock-solid partnership with Chad Marshall. “He's a strong, great defender. He's very dependable. I'm absolutely surprised he's not playing for the national team right now.” (5)

6. Colorado – Rapids coach Gary Smith hoped for a bump in form from his side's visit to the White House on June 27. He got it: Colorado has gone 5-1-3 since its foray to Washington. (7)

7. Philadelphia – Where would Peter Nowak have ranked on the list of potential Tweeters among MLS coaches before he started his account on Monday? (8)

8. Sporting Kansas City – What sort of sanctions will Omar Bravo and Peter Vermes incur prior to Wednesday's game with Portland? (6)

9. D.C. United – The Dwayne De Rosario-for-MVP train continues to pick up steam with each passing week. (10)

10. Houston – Despite its home dominance (7-3-3), the Dynamo have some work to do on the road in order to claim a playoff berth. Houston is the only non-Canadian team without an away victory this season. (11)

11. Chivas USA – For one of the few times in its relationship with the Galaxy, the Red-and-White holds all the cards. Robin Fraser and company must use that leverage to good effect in a potential Juan Pablo Angel deal. (12)

12. New York – Remember when the Red Bulls were supposed to boast the best defense in the league? (9)

13. Portland – Mike Chabala, Lovel Palmer and John Spencer probably didn't enjoy their return to Houston. (13)

14. Toronto FC – The pieces are starting to come together a bit, though the Reds still look rickety at the back. (15)

15. New England – The visits by Houston (Wednesday) and New York (Saturday) probably represent last chance saloon for the Revs. (14)

16. Chicago – Another week, another draw. What else is new? (17)

17. San Jose – A slice of luck would go a long way towards ending the current club-record 11-match winless drought. Maybe new Ecuadorian striker Edmundo Zura will provide it. (18)

18. Vancouver – Will the potential arrival of the divisive Owen Hargreaves really help the Whitecaps in any way, shape or form at this juncture of the season? (16)
