First two points are old news but your third point is really beginning to worry me. Our transfer policy has improved drastically in that we've picked up a truckload of players at an absolute bargain who look class (Dier, Alli, Toby, Big Kev), but then on the other hand we've drifted back to the bad habits of the late 90's/early 00's in terms of signing supposedly promising players who are then unceremoniously ditched after barely a year at the club. Njie, Yedlin, Stambouli, Fryers, now perhaps Son as well.
If players are really that bad that we're happy to offload them - often at a net loss - having barely been given a chance to impress, our scouting team needs to be put under some serious scrutiny. Perhaps this was part of Levy's reasoning behind 'encouraging' Mitchell to step down? Wouldn't surprise me, given how paranoid he's been about wasting money since Baldinigate.
