Arsenal are the favorites to win Champions League, and are still first in the Premier League. They have the best defense in Europe, and dominated in Lisbon for the first leg. They're doing all this, but, they're also slowly starting to unravel. They've been knocked out of two Cup competitions in the last month, and are coming into this match off a loss to Bournemouth. This team is tough, but mentally they're starting to break. I'm putting a little sprinkle, on the upset of the tournament for a Sporting side who won't back down.
