When the Seattle Sounders and Colorado Rapids take to the pitch at Dick's Sporting Goods Park on Sunday for the second leg of the MLS Western Conference final, all eyes will be on the midfield alignment of both sides.
Both sides play a similar style of the 4-2-3-1 formation, but the Rapids will be forced to tweak their system for the second leg after the yellow-card suspension of Sam Cronin, who picked up his second caution of the play-offs in Tuesday's first leg that was won 2-1 by the Sounders.
Coming up with a replacement is an easy job for Colorado boss Pablo Mastroeni.
