Is there a stat anywhere that shows player turnover - as Peterborough must be winning by a landslide, they seem to buy and sell anywhere from 5-10 players every window.
As for Barry - he is a glorified agent, running a football club, he is more suited to buying and selling than he is working on tactics.
And he's good at it too. I think he turns over a pretty steady profit for the club and along the way they have a steady stream of good players.
