I think its actually a lot higher than that now. Percentage of penalties saved over the last few years in the prem from 2020- 2024 season were 10.4%, 11.65%, 17.17%, 7.55%, Excluding penalty shootouts, Ederson has saved 3 from 26 penalties hes faced for us, an 11.53% save rate which compared to the saved rates over the last few seasons isnt at all out of line.
I agree we shouldn't expect a keeper to save a penalty that has been my stance throughout, right back to when the Ederson shitposting for not saving penalties started and that's my point here, the people that was constantly berating Ederson for not saving penalties are noticeably quiet when another keeper also fails to save a penalty, its almost like they didnt have a valid point.
