Not sure that's true at all.
Lets look at last season. Last 19 games of 2022/23 - 8 wins, 3 draws, 8 losses. 1.42PPG (54 points over a season)
Two seasons before that? Last 19 games of 2020/21 - 9 wins, 2 draws, 8 losses. 1.53 PPG (58 points over a season)
Pochs last 19 games in charge? - 6 wins, 6 draws, 7 losses. 1.26 PPG (48 points over a season).
Go back even further. Redknapps last season in charge? 7 wins, 6 draws, 6 losses, 1.42PPG (54 points over a season)
Now if we beat Sheffield United, which we will do. This will be our last 19 games of 2023/24:
9 wins, 3 draws, 7 losses. 1.58 PPG (60 points over the course of a season).
By the way, let's look at Villas last 19 games (and let's just say they draw with Palace). 8 wins, 6 draws, 5 losses. 1.58 PPG. IDENTICAL to our half of the season in terms of points... Of course they could lose to Palace which means they'd have done worse in the last half of the season than we have...
This most definitely isn't our worst run of results since Ramos or in over 20 years at all. And if anything, shows us that this is usually a typical Tottenham season.
Start well. Tail off a bit. Hit some form again. Finish weak.
