I don’t think it is realistic, but if they had to go to the Championship, do you think there will be players who want to stay and get up again, or they just look for an other Club? Which club would even be a possibility for the biggest city stars?
Sorry for my english
To make it as easy as possible for the players, move them to a team with similar name. Added benefit that the players can continue living in their houses, instead of moving somewhere new.
