You'd think anyone decent who has only been there a short while will have already been on to their agents, given the state of the club. They're going to have to take a huge risk this summer even if they lose only 1 or 2 of their better players.
There's an argument for signing players with a habit of winning, but we've got a big enough group now who win games more often than they lose, so anyone brought in from a struggling club can be turned around.
