Happy Boxing Day! The holiday, celebrated in the United Kingdom and most of its current and former commonwealth nations, is held annually the day after Christmas. It began as a celebratory day for servants who had to work on Dec. 25 and has since become a major shopping event, akin to Black Friday in the United States. It’s also a significant day for sports, mainly with the Premier League featuring rivalry games. Today’s lineup includes Manchester City vs. Liverpool, Hull City vs. Manchester United and West Ham vs. Arsenal.
