Yet, that's exactly hat happened in the end days of Poch, when losing to us in Madrid (and so meekly) was a massive setback for Spurs and everything changed within 3 months.
If you think that was just about one game you're wrong. We rode our luck massively to make it to that final and we had been terrible even in the Champions League that season, let alone every other competition. Poch had completely lost the spark and style of play that had got the team to where it was previously, which I guess at their peak was the 86 point seccond place league finish.
The loss in the CL final had very little to do with it in the end, that run simply papered over some of the cracks of a rapidly declining team.
Now, we're on an upward trajectory at the moment, things are already much better than the best I'd expected from this season even if we hit a down patch and finish around 6th or 7th I'd be fine as long as we keep seeing this style of play and then build on that between seasons.
