We were lucky to be in a situation where the match could be decided by the last kick of the game
If Gomes and others had shot on target, Sydney could have been 3-0 up before the 90 minutes elapsed
Nope. As the yellow from earlier in the game isn't carried into the shootout he technically wasn't on a yellow when he got booked in the shootout.
In saying that, he got the yellow for the way he was behaving with the crowd, then did the same thing multiple times again during the shootout so probably should have received a third yellow.
