It's safe to say that Chelsea supporters have had to put up with a lot in the last few years.
Yet they have also hired and fired seven different managers in five years - eight including current boss Jose Mourinho.
The second coming of the Special One, though, may have marked an end to all the uncertainty. The Portuguese boss has come full circle since leaving Chelsea in 2007 and looks calmer now than ever before in his role as manager of a football club.
And the 50-year-old has gone even further to reassure Blues fans about his long-term future this week, telling the Evening Standard that he 'belongs' to the club. Could Mourinho really be in it for the long haul?
“I’m not here thinking about my next move because I don’t want to have a next move," he said. "I’m here to stay. I belong to Chelsea, Chelsea belong to me.
“I think London is the only place in Europe where I can keep these little things of life. I can go to school and wait for my son and daughter and the parents feel me as another parent.
"I can go to walk on Sloane Street or Old Bond Street and if somebody disturbs me it is not an English person for sure. I can go to a restaurant, I can go to a cab and the driver be an Arsenal or Tottenham supporter and he enjoys speaking with me. This is not possible in Italy and Spain!”
With the Blues flying high this season, of course, Mourinho has plenty of incentive to go the distance.
Chelsea are in the last 16 of the Champions League, third in the league (just two points off leaders Arsenal) and into the next round of the FA Cup. Indeed, there is nothing stopping the Special One from adding another historic treble to his ever-growing list of personal achievements.
But Mourinho's bond with Chelsea seems to go beyond just the trophies and the record-books. There is something about the 50-year-old at Stamford Bridge that conveys comfort and homeliness; a homeliness that did not exist at Real Madrid and, perhaps, only to a lesser degree at Porto and Inter Milan.
No fireworks have flown this season; it has all been plain sailing. For now, at least, it appears Mourinho and the Blues are a match made in heaven once again. This time, though, it might actually last...
Could Mourinho stay at Stamford Bridge for the rest of his career?
