Think that one today is a bit iffy, personally. Son's challenge was nowhere near the ball and does impede the player imo.
Moses chooses to let Son impede him, then still dived without there being any touch at all. The way everyone's classing it as a nailed on penalty, imo, just shows how much it's seen as fair-game now. Absolutely hate it.
Son slides wildly inbetween Moses and the goal. If Moses touches the ball first it's a pen.
Agree the dive is horrible though. Despise it.
