It's not a fetish. Simply compare numbers. Wins, goals conceded, shots conceded, they were better. The lack of honesty is on your part.
We conceded 4 goals during the run of 14 wins in 18/19 when every single point was decisive. Plus, last season we defended as a team better than in 18/19, our pressing game was better. In 18/19 we had players like Kun and David who weren't as good and useful at high pressing as Foden and Jesus. Plus we had Rodri who is a better DM than Gundogan (who played at DM after Ferna got injured in February 2019).
Simplistic comparisons of conceded goals and chances won't tell you the whole truth about Kompany/Laporte vs Dias/Stones. I like both Stones and Laporte, but think Laporte has been more consistent since his arrival and is a bit more physical and hard than John. Last season was the only one in which Stones was better than Laporte, and the latter arrived here 4 years ago.
