Yes because the sign of champions is playing badly yet winning that isn't a famous saying at all.
Performances only matter when results are not happening. You are getting results.
So what kind of chances have you made? Care to point out the source you are using that breaks down a comparison of
Where you chances are created from?
Goals are conceded from?
Saves made from yard distance ?
Or could it be your looking at a general stat and placing importance on it because you have an agenda.
Goals Conceded
18/19 he faced 148 shots on target (3.89pG), only 5 keepers faced fewer and they played for Man City, Liverpool, Chelsea, Everton & Leicester.
19/20 Dubravka has faced more shots on target than any other 'keeper in the league (161 or 5.6pG). (footchart.co.uk).
So he's been significantly busier this season compared to last.
26/48 Goals conceded come from Open Play, 13 from set pieces, 2 from counter attack, 6 penalties, 1 own goal.
27/43 open play, 12 from set pieces, 3 from counter attack, 0 penalty, 1 own goal. (whoscored.com)
So the shots that do get past him come from roughly the same situations aside from penalties. And I'll leave the VAR issue the fuck alone. Per Game we're conceding more across the board, bar penalties.
49 of 489 shots taken against us were in the 6yd box or 1.29 pG (6th highest), 293 in the 18yd box or 7.71pG (6th) and 147 outside the area or 3.87pG (4th lowest).
53 of 444 shots taken against us are in the 6yd box or 1.83 pG (highest in the league), 231 in the 18yd box or 7.97pG (4th highest) and 160 from outside the box or 5.52pG (5th highest). (combination of whoscored.com & footchart.co.uk)
So we now allow more shots in the area per game, than we did last season. Obviously when the season ends we can stack them up total v total instead of pG.
Will we concede 45+ shots before the end of the season? Well, we're averaging just shy of 15 per game, and we've 6 games left. 3 of them against Liverpool, Man City and Spurs.
Last season we were 10th in terms of expected goals against on 57.55, this season we're 4th worst with 55.41 already.
tl;dr busiest 'keeper in the league, facing more shots in the box than any other. This wasn't the case last season.
I'll try and supply the rest of the things you asked for.
