Lionel Messi Couldn't Hide Being Shocked When Barcelona Found Themselves Down 1-0 To Celtic

Barcelona's home leg of their UEFA Champions League tie with Celtic was supposed to be easy—let Barça's superstars overwhelm the Scottish champs and build an early lead. That isn't how it worked, though, as a 17th-minute Celtic goal silenced the Camp Nou crowd—and superstar Lionel Messi. Barça would eventually equalize before the end of the half and then with seconds remaining knock in the match-winner.
