It’s a quote from the film The Dark Knight.
Context is Batman is Gotham’s hero, but obviously is doing Batman things. There’s a Prosecutor who is cleaning up the streets the “right way”, but he then becomes Two Face and kills some people (the public don’t know this) - Batman in order to protect the reputation and legacy of the prosecutor of the City doing the right thing and operating legally and doing things by the book then takes the blame essentially for Two Face’s crimes.
Batman is the real hero, but not the one it “needs” (vigilantism). Commissioner Gordon is aware of all the events but goes along on this premise, he knows they won’t catch Batman but also they’re better off having a legacy of legal recourse than a legacy of relying on a man dressed as a Bat as the one protecting the city.
Goldbridge probably hasn’t applied any critical thought to the quote because he’s a total clown. But an incredibly generous reading is him implying Ronaldo is taking a hit in his legacy in order to target the Glazer’s and faults with the club.
