Spurs have collected just two points from their opening three games in the Premier League to leave some fans discontent with the work done by the new manager, who was sacked by Chelsea last season.
Conceding a late equaliser to Norwich at the weekend ensured that Spurs drop down to 20th in our rankings, below PSV Eindhoven.
This is the lowest Spurs have slipped in the rankings since a brief spell in April 2012, while their previous time spent at 20th came in August 2011.
The only other change in our rankings saw reigning Serie A champions Juventus climb a place to 15th, ahead of Valencia.
The Old Lady, still suffering from their spell in Serie B as they slowly climb the rankings, beat Udinese 4-1 away at the weekend.
HOW IT WORKS
To determine our Power Rankings, we use the Euro Club Index, which scientifically analyses hundreds of thousands of matches from the top divisions in all European nations as well as Europa League and Champions League games.
The Index takes into account all matches played over an eight-year period but with recent results carrying more weight than older ones.
The performance of a league's teams in the Champions League and Europa League reflects the rise or fall of the sporting level in that league. So, for example, if English teams perform well in Europe, all Premier League teams receive a small bonus in their ECI score. The ranking and its predictive power are thus made even more accurate.
