Ederson has the same problem though, exceptional ball playing keeper like Raya but you don't look at him as opposition and feel the intimidation factor.
That is why Alisson and prime DDG were just that far ahead, it just seemed impossible at times to score past them. Keepers still have to be exceptional shot stoppers even if the game has evolved beyond being just that. Raya is too small to be really good defensively, 6ft only, I'd worry for us with corners etc.
For me, I still think we made a huge mistake in dismissing Martinez. He is 6ft5, good shot stopper, great at saving penalties, good distribution. He is very well rounded is what I am saying, there are no glaring weakensses to his game or mental profile. If we paid the money to Villa he'd probably come back, but Arteta seems to burn the bridge and have no interest in repairing it. He is wasted at Villa, really is. The reason why his career didn't pick up at Arsenal is because his game was ahead of its time, at a time when Wenger's conception of the game had become outdated. He's a victim of circumstances.
