Interesting how England scored twice after Grealish came on. Maybe Southgate should, I don't know, try starting Grealish?
It's tough because you could say that Saka earned his start and with the formation Southgate uses, there's little room for other replacements. He's set on two holding midfielders at all times, can't drop Kane, and can't drop Sterling either. So there's really only one spot for Saka/Grealish/Foden/Sancho.
