Although the deal seems unlikely to be concluded until after the finals, Sagna's representative Laurent Gutsmuth insists a move to City will go ahead with Napoli not considered an option.
"It's true that we were contacted, but for information only. We never spoke about figures," Gutsmuth told AreaNapoli.it.
"He should be signing for Manchester City."
Sagna is expected to put pen-to-paper on a three-year deal worth £140,000-a-week to sign for City.
