Goal understands that Manchester City are lining up a sensational swoop for a world-class centre-half this summer - but the proposed deal is shrouded in secrecy.
The Premier League outfit had been linked with Southampton's Virgil van Dijk before the Dutch defender apparently indicated his preference for a move to Liverpool, while Pep Guardiola is a long-time admirer of Juventus ace Leonardo Bonucci, once describing the Italian as one of his favourite players.
However, the fact of the matter is that trusted sources close at the Etihad Stadium are refusing to give away any clues as to the identity of the mystery transfer target so as to avoid potentially scuppering what it is being described as a "complex" deal.
Above, though, we take a look at just who City might be considering signing to shore up their defence for the upcoming 2017-18 campaign.
