Wish him all the best and may be a decent fit if he can turn the ship around.
Charlton have the size, stadium. and had the fanbase before. If he's successful there and they back him, no need to jump ship again.
Heard a Stains fan on radio excusing his time at Stoke with "well all good managers have at least 1 club where things don't go well"
flipside is, maybe some managers only have one club where things do go well.
