For the pair are not fond of each other, both sharing the common experience of having managed Real Madrid, albeit with differing success.
Chilean boss Manuel Pellegrini was infamously the man in charge when Madrid splashed out staggering transfer fees for both Cristiano Ronaldo and Kaka, and led Real to a record points total.
The problem was, Barcelona went even better, and ensured Pellegrini's spell at the Bernabeu failed to result in the deliverance of any La Liga titles.
When Pellegrini was fired, the man who took his place was Jose Mourinho who would fare slightly better, winning one La Liga title out of a possible three, and going onto eclipse Pellegrini's record.
Both managers have been in contact this season, although not cordially, when Real Madrid have taken on Pellegrini's Malaga.
Madrid won 6-2 when the sides met earlier this week, but prior to that Malaga got one up on Real, beating them at a crucial stage of the campaign and derailing their season, with Barcelona essentially having had the title won since late last year.
Mourinho would have some harsh words to say about Pellegrini, branding the coach a 'loser' for failing to win silverware with Madrid, and questioning his ambition.
"Second place is just the first loser. If Madrid were to fire me, I wouldn't go to Malaga. I'd go to a top-level team in Italy or England."
Now it appears Pellegrini is about to do just that with City, and could come face to face with Mourinho, who he has had his own bite at:
"I don't like coaches who are only interested in results. The concepts of spectacle and creativity and fundamental to me."
For it is that aspect of creative and exciting football which contributed to Abramovich removing 'The Special One' in the first place. He may regret it now, but Pellegrini certainly believes his principles makes him intrinsically better than Mourinho.
With the pair likely to clash in the transfer market in the race to sign Isco from Pellegrini's soon-to-be former club, who Chelsea are claimed to be setting up a partnership with, the future should certainly be entertaining.
Supporters of the Premier League love personalities, and when two managers with a history of bitterness and perhaps even professional jealousy head towards our shores at once, it can only be a good thing.
