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
Spurs didn’t just lose to Chelsea, one starting CB on three game suspension and another out for weeks or (potentially) months. Madison is out till January and none of your replacements are anywhere near the level of those three.
If Son goes down the season is damn near a wash. Not to mention Ange proved himself tactically stubborn when he COULD HAVE pulled out a point from a lackluster Chelsea.
In a vacuum, yes it’s just one match. But contextually I can’t think of one match that could have gone WORSE for Spurs.
