If you want to win at the Etihad Stadium, you should focus on two things: good defense and discipline.
But Arsenal did neither of those things on Saturday, and for their troubles, they were hammered 5-0.
After just 12 minutes, the Gunners were 2-0 down to the champs, owing to two terrible defending mistakes.
Granit Xhaka was sent off for a two-footed lunge, and they conceded a third goal shortly before halftime.
With that red card, Xhaka has joined David Luiz and Fernandinho as the Premier League’s bad boys in recent years.
STAT: Since the start of the 2016-17 season, no player has been sent off more often in the Premier League than Granit Xhaka (4, level with Fernandinho and David Luiz).
