Burnwinter I will give the man credit just for being on the pitch at this point given how well we're doing. Even an inanimate carbon rod can become a hero under Mikel Arteta.
I think you're doing him a disservice here. Raya is doing his part if creating that low xG environment. Think back to his early season performances and how uneasy we felt each time he got the ball, or each time he came for a cross, or how out of sync our centre backs were with him. That sort of thing infects our whole game.
There's now a measure of calm and assuredness now that surpasses the Ramsdale days and it plays a part in how we're performing.
