I 100% accept Pogba wasn't good against Southampton (I was at the game). But why does he only dig out at certain players? - We all know how abysmal Matic has been for months. It seems criticism is only reserved for some and not others.
Exactly, lambasting a player after a game where he is particularly bad is fair, even though you should do it with measure. But when the worst offenders are continuously exempted from blame then something is wrong the only excuse would be that Pogba is the only one that can take it while the others would crumble, in that case that's somewhat a sensible idea to not lambaste Lukaku, Matic or Young.
