What did Paul Scholes say that triggered this? Pogba should do something about this, he was given the captaincy (though Valencia is injured), which is as high an honour as you can get playing for this club. I'm sure he won't fire him but atleast get him to give an apology to the club.
That being said, if Scholes did criticize Pogba recently, I think this comment is more a dig at Scholes to challenge him that if he doesn't like Pogba then he should become the sports director and sell Pogba himself. I don't necessarily think it's Riaola saying that he wants Pogba to be sold. Obviously insanely dumb of him to make those quotes, and again illustrates how volatile a character he is, but I don't think its worrisome in terms of him wanting to sell Pogba urgently.
