Pep Guardiola and Jose Mourinho started out as friends when Guardiola was a European conquering midfielder and Mourinho was a simple translator.
Fast forward 15 years and Jose Mourinho is battling with Pep Guardiola for a La Liga title.
Their rivalry is one of the fiercest managerial rivalries of all time. Everything that Mourinho did was surreptitious and sly, while Guardiola tried to maintain the moral high ground but was quite often drawn into an angry tirade against the self-proclaimed "Special One".
Their competitiveness saw no bounds as it continued on to the pitch. Red cards flying everywhere there was no stopping players like Pepe and Dani Alves from pulling off dirty antics left right and centre.
Now there's been another twist in the saga. It now seems that Roman Abramovich wanted Guardiola instead of Mourinho.
The side that Roman Abramovich has been building over the past couple of years has been filled with the intent of becoming a side that can pass the ball sharply and quickly without letting the other team get a touch.
Abramovich brought in players like Oscar, Juan Mata, David Luiz and Eden Hazard to create chances for Fernando Torres (or Radamel Falcao, or whoever he fancied).
He probably didn't envisage his side going back to dull counter attacking football which he got rid of Mourinho for in the first place.
By the time Mourinho had left, many had grown tired of being a disliked team and a team who people considered boring. He'd tried all avenues and he had finally conquered Europe, all he needed now was to conquer the hearts of the neutral.
In order to do this he needed someone who could get his new Trio of exciting talent to click. He wanted Guardiola.
He wanted a man who could conquer Europe again and conquer the hearts of the atheistic fan. He looked for every excuse to get rid of Roberto Di Matteo a man who we can question his desire to hire in the first place.
He needed someone to make his side click but Guardiola chose, as any sensible manager would, a different option.
Abramovich had now exhausted most top managers in the world including four Champions League winners in Carlo Ancelotti, Jose Mourinho, Roberto Di Matteo and Rafa Benitez, a World Cup winner in Luiz Scolari and one of the best young managers around in Andre Villas-Boas.
He was left with only really one option, to turn back to a Chelsea hero but a man he fell out with, a man who we all assumed would one day return but a man who didn't actually want to come back either.
For according to El Pais it seems that Jose Mourinho was devastated when failed to get the United job.
So it is fair to say that Jose Mourinho's return enlightened wasn't quite as intended as we all believed.
Abramovich intended to recruit Mourinho's arch rival and Mourinho planned to be recruited by Chelsea's arch rival.
It leaves you to wonder how long will Mourinho last and whether he possess the same fire we once saw burn in his talented eyes, when he stepped onto the threshold of Stamford Bridge, looking to prove himself as not just a one off success. The answer will be undeniably answered in due course.
