Mourinho and Guardiola have each won 20 major titles during their managerial careers, but the spaniard has been more successful in recent history, leading city to a record-breaking premier league title last season.
City have continued their dominance this season with Sunday’s 3-1 derby win putting Guardiola’s league leaders 12 points ahead of Mourinho’s eighth-placed United after 12 games.
However, Maradona insists Mourinho is “the best without doubt”, suggesting Guardiola is only out-performing his counterpart due to the financial backing he receives from City’s Abu-Dhabi owners.
In an interview with Spanish publication Marca, Maradona said: “For me yes, Mou is the best. I would give Pep the merit of taking advantage of the launch that Johan Cruyff gave him.
“I have said on more than one occasion that tiki-taka was not invented by Guardiola. It was ‘flaco’ Cruyff. At the moment Pep is able to choose any player in the world that he wants. That way tiki-taka is easier.”
