Do you have quick numbers at hand for the same comparison between Tuchel/Lampard?
It looked like a win/win in both cases at first, and I guess numbers will say that Chelsea improved a bit, but in the end, I wonder how much these changes benefit the two clubs in the long run...
In PL 20/21:
Lampard: 8W 5D 6L, win percentage of 42% (1.52 points per game)
Tuchel: 11W 5D 3L, win percentage of 58% (2.00 points per game)
In total for Chelsea:
Lampard 84 games: 1.75 points per game
Tuchel 29 games: 2.07 points per game
A significant improvement compared to Poch/Tuchel tbf.
