You’re allowed an off day. Reminder
Leicester got battered 5-1 by Arsenal at home and still won the league
Man City lost 4-0 to Leicester at home, still won the league
Liverpool lost 3-0 to Watford, still won the league
Man United lost 5-0 to Newcastle and 6-3 to Southampton, still won the league that season
IMO it’s because they are far exceeding expectations early on without the depth to make it to the end of the season. This game showed an error in strategy that will be exploited if it continues and the coach made it sound like that’s how they will continue to play.
