They say you should never go back, but it is working out pretty well for Chelsea and Jose Mourinho.
Rafa Benitez still has family who live in Liverpool and is looking to either return to the club or get a job with a national side in order to see them more.
He did of course win the Champions League with Liverpool and is still a hero to the fans, getting a warmer reception as an away coach for Chelsea than he did from the Blues.
