I think Saliba tends to be both more eye-catching and pleasing on the eye, but hasn't quite nailed down the basics in the way Gabriel has.
I find it hard to look beyond Odegaard really. Rice and Gabriel are in the mix for consistently being at a high level, but what Odegaard brings is just irreplaceable for me, even if in certain games he hasn't been able to shine like we know he can.
I don't think Saka is anywhere near a conversation for player of the year as it happens.
