I dunno, feels odd for Si of NSNO to post something like that, was on that forum years ago and just doesn't seem like something he'd make up. Although things change and could have fallen victim to farming clicks like a whopper.
Him learning his trade for the year with Grealish is such a bonus as well, just hope we are somewhat patient with him and don't write him off because he was expensive and took a while to get over the line.
