They have only conceded a goal in 6 of their last 24 matches.
For context, we have conceded in 13 of our last 24 matches.
They are rock solid.
We play a higher line, we rarely went behind in a lot of those game and we don't play half as conservatively when we've gone ahead. Plus we've played more top teams who can hurt teams with pace in those games.
Liverpool, Everton, West Ham, Wolves, United, Leeds, Villa, BVBx2, PSG make up 10 of the 13 games we conceded in. That's not bad. We won most of them games.
Swansea and Chelsea in the FAC cup against weakened/much changed City teams and Southampton in the league where they scored a penalty early in the game and another while we were 4-1 up. Those make up the rest of those games.
It's not hard to cherry pick stats and convince yourself of something, we can all use whoscored and what not.
Ederson is in the lead for the golden gloves, 18 clean sheets to Mendy's 16. Chelsea have conceded 20 goals from open play this season to City's 12 all season. Including shipping 5 goals to Big Fat Sam's West Brom under Tuchel.
I could see it in this game tonight anyway, besides all the statistics, the eye test can tell you just as much. They played a much worse team, with far less pace and attacking threat and their keeper was called into action numerous times. PSG would have beat Chelsea on the form they showed against us IMO.
edit: It is 13 games I stand mistaken, can't believe I had to go back and count them. Which stat site did you use or did you count manually too?
