Ex-Manchester United manager Jose Mourinho does not feel he was given the same opportunities or conditions for success as Pep Guardiola and Jurgen Klopp at Manchester City and Liverpool.
Mourinho's two-and-a-half-year tenure at Old Trafford ended when United were beaten 3-1 at Liverpool last December, amid a poor run of Premier League results.
Having arrived in Manchester at the same time as Guardiola ahead of the 2016-17 season, a renewal of the duo's rivalry from their time at Real Madrid and Barcelona was anticipated.
But this failed to materialise, despite United lifting the EFL Cup and Europa League during Mourinho's initial campaign, with Guardiola's City racking up 100 points to become champions in 2017-18 – 19 clear of the Red Devils in second place.
It is Guardiola's duel with Klopp that has captivated the Premier League this season, with both City and Liverpool having broken through the 90-point barrier with two games remaining.
Mourinho made Paul Pogba the most expensive player in the world after becoming United boss, while a mega-money package persuaded Alexis Sanchez to move to Old Trafford instead of the Etihad Stadium last January.
Nevertheless, the former Chelsea boss feels the more sustained support Guardiola and Klopp enjoyed was clear.
"I would love to go to a club and be in conditions to do what Jurgen and Pep did," Mourinho told beIN Sports, while working as a pundit covering the UEFA Champions League semi-final between Barcelona and Liverpool.
"If you look at the [Liverpool] team that started the game, how many of them were there when Jurgen arrived? A couple," he said.
"And when Pep was not happy with the full-backs he had [at City in 2016-17] and in the [next] summer bought four [three] full-backs that he liked.
"When he bought one goalkeeper like Claudio Bravo and was not happy with Claudio Bravo, the next season he bought Ederson.
"When Jurgen is in the club and wins absolutely nothing for three-and-a-half years and he still has the trust, still has the confidence, still has the conditions to try to keep going and going.
"Probably this season they have a big chance to do it – the first time that they win a trophy.
"In my next job I will not be starting a conversation without knowing exactly what the club wants and what the club has to give in terms of structure and the club objectives."
Gary Neville said his former club were in hindsight wrong to appoint a manager like Mourinho, who did not align with United's traditional philosophy.
Mourinho scoffed at this assessment and drew attention to a famous triumph over Guardiola's Barcelona with Inter in 2010 to suggest his reputation as an ultra-defensive coach is unfair.
"You are in the direction of a lie told a thousand times become truth and it is not true," he said.
"When people remember the incredible match that Inter played in Barcelona in the Champions League semi-final with 10 men, people say that was a masterclass of defensive football but was two buses parked.
"You don't say that two weeks before [it was] Inter 3 Barcelona 1. We put ourselves in the position to go there and defend that result, playing with 10 men against the best team in the world, because two weeks before we beat them 3-1 and it should be four or five."
Similarly, he felt Antonio Conte's Premier League triumph at Chelsea in 2016-17 was judged by different standards to his three over the course of two spells at Stamford Bridge.
"When I came to Chelsea for the second time and we were champions, we were champions when we were not the best team in the country," Mourinho added.
"To be champion when you are not the best team in the country you have to be more strategic than philosopher.
"And then, when Chelsea was champion again with Antonio Conte, Chelsea was a counter-attacking team – very defensive and phenomenal on the counter-attack.
"Once more they did it by the strategic point of view. But, because it was Antonio and not me, you didn't mention it."
