ever heard of David de Gea or Pickford?
de gea makes those on a weekly basis
Not like that, he makes technical errors. Pickford ironically would do well in the Bundesliga because he's looking for the next phase of play to launch the ball forward, without actually having the ball under control first. There's basically only two mistakes that keepers make - technical or concentration. That Liverpool one was classic.
In my opinion it's the style of goalkeepers in Germany that cause these highlighted mistakes, which is created by the attacking style of football in general. There's so many examples of virtually throwing the ball in the net, which is simply because they are thinking about the next attacking play forward. Also a couple of bizarre ones that I can't even explain.
With Italian keepers a lot of the ones I can think of in the last 10 years involve miscontrolling the ball with feet and losing the ball. Italian keepers don't tend to be as good with their feet, even up to Donnarumma today. Some technical errors with the hands, of course, but I'd say most are concentration for keepers across the board.
