Manchester City are eyeing Bayern Munich midfielder Kingsley Coman.
The Frenchman is on-loan at Bayern from Juventus.
Leggo says should Bayern turn down a permanent deal for the player, the Bianconeri have two options.
A relaunch of his career in Turin could be on the cards, but waiting in the wings is Pep Guardiola, who holds his ex-player in high esteem.
Guardiola would love to bring Coman to City in 2017.
