Qwest Field will play host to the night fixture and the Sounders are anticipating that they will beat their current record of 36,593 which was set against Portland Timbers last month.
Sounders general manager Adrian Hanauer expects a crowd of in between 45,000 and 50,000 for the clash and goalkeeper Kasey Keller says it will be great for the Seattle fans to come out and see both their team and Red Bulls star Thierry Henry in action.
"The cool part about it is our fans are coming to watch the Sounders, they're not coming to watch Thierry Henry," Keller said.
"That's an added bonus if he's playing, but it's not going to make a difference. More importantly, our fans want to leave the game knowing we got three points."
