The newly formed MLS side are yet to play a competitive game, but already well-known in English football due to their close links with the reigning Premier League champions.
City co-own the Big Apple-based side with Baseball giants the New York Yankees, and made headlines for this relationship by signing Frank Lampard for the current season.
Demichelis could, though, make the opposite switch, moving from Eastlands to North America when his contract expires in a little under six months’ time.
Although happy to pen a year-long extension, the Argentine may not be asked to stay on, with the club’s plans not yet known.
This has alerted NYCFC, who have a Designated Player slot free for a high-earner and are keen on a centre-back.
The soon to be MLS side have already agreed to sign Lampard at the end of the Premier League season and have added David Villa to their roster.
‘Lamps’ was believed to have joined NYCFC from Chelsea last summer, but the veteran midfielder’s extended stay – he will remain at the Etihad Stadium until the end of 2014/15 – was agreed as the deal was only a pre-contract one – which is due to kick in in a few months’ time.
