This site carries comments recently made by Gabriele Marcotti on an Italian football podcast called Goalazzo:

He basically pinpoints the rumours as being anchored in the conspiracy theory that Agnelli and a close ally would use their UEFA positions to get City a CL ban and thus make Pep available to Juve. He points out that, if City do get a ban, it almost certainly won't be next season and suggests that manipulation of the Juve share price is behind the story. Nothing that hasn't been suggested elsewhere but Marcotti has an excellent reputation and an Italian background, so I thought it worth posting.
