William, along with Rui Patricio and Daniel Podence, has had his contract rescinded following a vicious attack by 40 men during a training session at the club’s academy in mid-May, which has led to players wanting out of the Lisbon club.
The 26-year-old, a Euro 2016 winner with Portugal, has become the third player to present his letter of termination to Sporting, making him available on a free transfer.
City are one of several English clubs to have monitored the stocky midfielder for a number of years, and the opportunity to snap him up for nothing this summer may rekindle their interest.
Of interest, Pere Guardiola, the brother of Pep and co-owner of Girona FC with the City Football Group, represents William, which could give City an advantage if they still have any interest in Carvalho. Girona themselves could also be an option if his wage demands fall within their financial capabilities.
Everton, now under the tutelage of Marco Silva, have been linked with a move for the player in recent days and could be another option.
City were also linked with another of Sporting’s stars, the speedy winger Gelson Martins, last summer, and if he follows William, Patricio and Podence, a host of clubs will be interested in acquiring him.
