The Manchester City left-back suffered cruciate knee ligament damage against Crystal Palace back in September, bringing a cruel end to his promising start at the Etihad, following a £50m summer move from Monaco.
Mendy is not due to be fit until the end of May, although the powerful 23-year-old has not given up on representing France at next summer's World Cup finals in Russia.
And the outgoing star is understood to be already ahead in his recovery, posting footage earlier this week of him working in the swimming pool at City's Football Academy campus.
Mendy is now walking unaided and the Citizens are confident his knee will be stable enough to increase his rehab over the next few weeks, with Pep Guardiola receiving positive updates on his progress.
The City boss has deployed midfielder Fabian Delph to fill the big defensive void left by Mendy's injury, to surprising effect, although he is still expected to sign a recognised left-back in January.
