Can Chicago become the location of two sporting miracles in the space of week? On Wednesday the Cubs won the World Series for the first time in 108 years, and today Ireland will hope to beat the All-Blacks for the first time ever.
They came heartbreakingly close in 2013, and have been waiting for another chance ever since.
New Zealand are on a two year, 18 game winning streak. Not even the post - World Cup loss of experienced players like Richie McCaw, Ma'a Nonu and Dan Carter has slowed them down.
It's a huge challenge for Ireland, but all winning streaks have to end eventually, right? Should they pull it off, you'll hear the screams all the way across the Atlantic.
