The clean sheets argument again. As mentioned earlier in the thread by
@King Azaz the Unabridged , in 2005 we kept 19 clean sheets with a combination of Carrol and Howard, both of whom were deemed to not be good enough. Ederson has more golden gloves than De Gea and in half the time, is he a better shot-stopper than De Gea?
Preventing shots is way more important for goals conceded and thus clean sheets than a goalkeeper's shot-stopping ability. The old adage that "you miss 100% of the shots you don't take" has a counterpoint for defensive players: "you save 100% of the shots the opposition doesn't take"
In the 17 games we kept clean sheets:
- Averaged 2.59 shots on target faced
- Had 12 games where Dave had to make 3 saves or fewer
- Gave up 0.46 post-shot xG on average with 9 being 0.5 or below. This implies that an average goalkeeper would keep a clean sheet more than half the time in those 9 fixtures. In these games it was the defence that kept the clean sheet, not the goalkeeper.
- The only game we gave up more than one post-shot xG and still kept a clean sheet is the Leicester home game, where he pulled out the save of the season in my opinion as well as one other very good one. This is the one game I would say he earned a clean sheet that the defence did not deserve. He did this three times in 2017-18 by the way, back when he was still elite.
- That leaves 7 clean sheets where he faced post-shot xG of between 0.5 and 1, these are a joint effort between the goalkeeper and the defence
In the remaining 21 games:
- Averaged 4.67 shots on target against, so getting on for double
- Dave made around the same number of saves as he did in the clean sheets
A team that prevents shots will concede fewer goals and have more clean sheets than a team that concedes more with a better goalkeeper.
