His long association with the Old Trafford club will make it harder for him to win over the City fans and it could be a dilemma for him to join the bitter rivals of a club he has supported as a boy - Evans' wife even works for United's in-house television station MUTV.
Do you think Evans would fit in at City?
Manchester City boss Pep Guardiola has reportedly made a shock move for a former Manchester United player.
In fact, the great Sam Lee of Goal is now reporting that Evans has already agreed to leave the Baggies and move to the Etihad.
The Frenchman has been training with the Blues in recent weeks and is now with the first-team squad in Girona, but is only considered a temporary option while other options are pursued.
Evans began his career in England with Manchester United and went on to make nearly 200 appearances in all competitions for the club, winning three Premier League titles and two League Cups.

"But this time previous year, Arsenal were interested in him as well".
A product of United's academy, Evans made 198 appearances for the Red Devils and won six major honours before eventually falling out of favour under Louis van Gaal and joining West Bromwich Albion in August 2015 in a deal worth an initial £6m ($7.7m) and a further £2m in add-ons.
The 29-year-old earns £75,000-per-week and City can easily improve upon that and hope a new bid of around £20m will now be enough to convince Tony Pulis to part with his man.
Mbappe was the subject of a €40m bid from City last summer and the Premier League club will fight to secure his signature this summer until he formally commits to another club, or signs a new deal at Monaco.
