He's been nice because he's just gotten here and hasn't wanted to rock the boat too much, but I think this is coming.You could see that during the parade.
Think that's a big part of Frank's problems, he isn't Ange, he doesn't have ange's charisma or way with people so I don't think they respect him much especially with the football he coaches.
If Frank had the stones then he'd drop 4 or 5 senior players for kids or fringe players to stamp his authority
With players back and, hopefully, some decent players in in the window, we might see him begin to get the Franking machine out to stamp that authority from January onwards, looking towards the summer window and who he wants out.
