Pep Guardiola is the proud owner of the two greatest teams in football history.
Well, at least, that's according to statistics with the Manchester City manager having held the reins of the 2012 Barcelona and 2014 Bayern Munich sides that have conquered all other male squads.
Guardiola is already revered as one of the greatest managers in history for his uncanny ability to win trophy after trophy after trophy and now the data has given him a major argument in the GOAT debate.
Pep Guardiola shines in statistical ranking
Over at clubelo.com, a complex algorithm is used to rank the greatest male teams in history with the peak of their 'Elo Rating' comparing the sides by how incredible they truly became in their prime.
You can read more about how the totals are calculated here, but the moral of the story is that it measures a team's capacity to beat another in direct competition with only one value per club at any one time.
So, if we're being truly accurate then the data shows that Guardiola's Barcelona side on April 15th, 2012, is the greatest in history, followed by his Bayern team on March 26th just two years down the line.
And with the clubelo.com rankings factoring in teams from across footballing history, whether that be the Real Madrid sides of the 1960s or Hungarian outfits of the 1950s, it really is nothing to be sniffed at.

Incredible teams everywhere
Goodness me. It's hard to keep it all together when you're scrolling past legendary teams who were stacked with the likes of Cristiano Ronaldo, Lionel Messi, Zinedine Zidane and more.
Nevertheless, while it's not expressly stated, we can only assume that just European teams were in contention because it's certainly curious that, say, the legendary Santos team of Pele's era is absent.
And the algorithm is by no means perfect when you consider that a trophyless Arsenal side from the 2000s somehow finds themselves above the Budapest Honved team spearheaded by Ferenc Puskas.

However, imperfections aside, there's no denying that it's a fascinating outlook on what the cold, hard numbers suggest are the greatest ever male sides to play the sport that we love so dearly.
And while you could pick faults in any equation until you're blue in the face, it can't be a coincidence that the two teams that ruled them all were both managed by the exact same coach.
Whether you like it or not, there's no longer any denying that Guardiola is firmly in the conversation for the greatest manager in football history.
