Post-shot xG difference is amazing tool at indicating goalkeepers that are good on average in savings shots and to observe so called “hot goalie” effect we also observe in hockey.

People forget that in the past the award was yearly not seasonal.

Sneijder got to his normal level past WC while Messi… got his casual 20+/10+ (LL/CL) in the autumn. Generally whole Inter team got to ground level.

Messi wouldn’t receive 2023 award on 2010 rules as everyone would ignore Miami part (he would probably receive 2022 if voting was moved to cover WC etc).
