Shaun Wright-Phillips says Chelsea can learn from Manchester City's owners.
SWP played for both clubs, though was not at City when they were bought out by Sheikh Mansour.
Given what City have done with the money, the players they've bought, the infrastructure they've built down to the academy and what they've done to the stadium and the areas around Manchester, you have to say City [have handled things better than Chelsea]," Wright-Phillips told the Daily Star Sunday.
"The longevity and how well they're doing still is so impressive. Not to take anything away from the way Chelsea did everything. I thought Roman did everything right for the club, but the difference is with City they're doing it year after year after year, and that's not something that comes easy. The mental challenges behind that and knowledge of the club to keep getting better and bigger."
SWP continued: "We all knew what they wanted to do and how they wanted to achieve it. We didn't think it would happen so quickly but the managers and signings they made along the way made that all possible.
"[Roberto] Mancini, [Manuel] Pellegrini, Mark Hughes I thought did superbly. Now you've got the main man Pep who's probably the best manager the Premier League's seen in a very very long time, if not ever. He's taken the game forward, raising the standards of other managers like [Jurgen] Klopp, [Mikel] Arteta, [Roberto] De Zerbi and [Mauricio] Pochettino. There are so many managers that have progressed from what Pep has brought to the table."
