It's not just the fact that Tottenham have dropped eight points in their last four Premier League outings that gives cause for concern. It's the manner in which they have dropped them. In 1-0 and 2-0 defeats to Manchester United and Arsenal they were far too passive, almost as if their only ambition was to come away from Old Trafford and the Emirates unbeaten. They lacked the ambition to live up to their prematch billing as narrow favourites and got punished for their mistakes.
Even more worrying was last Saturday's 1-1 draw at home to West Brom. Spurs started the game as if they were suffering from a collective hangover.
