Jurgen Klopp had an important conversation with wife Ulla as he prepared to leave Mainz for Borussia Dortmund after 18 years as player and manager in 2008.
Players, staff, management and fans cried when Klopp said his goodbyes and that, for him, could not happen again.
'I told her we cannot be that close to another club,' Klopp said. 'It's not normal. It's nice but it was not what I was looking for.'
It took under a year at Dortmund to realise the same sort of feeling was resurfacing.
