Forget Williams. He left to be closer to family, so unless Swansea or Nottingham has moved, he won't be back, plus how can you say he wouldn't do the same again as soon as a job came up. Swansea wasn't the first time he nearly left if all is to be believed.
He also moaned about the players he needed & was also on a dire run when he left.
His pattern of play was the same as SM's.....predictable
