The Argentine, 21, signed for £40m from Manchester United last summer but has failed to make an impact under multiple managers, including Liam Rosenior, who seems reluctant to give him chances in the side.
Now, he has deleted all the Chelsea posts from his TikTok account, with the only four remaining videos dating from his time at Manchester United.
Garnacho also reposted a clip from a United supporter account that paid tribute to his spell with the Red Devils in what feels like a clear message to Chelsea, where reports claim he is unhappy due to his lack of support and game time.
The winger has started only seven of Liam Rosenior's first 20 games in charge, with him featuring against lesser opposition such as Pafos, Charlton, Hull City and Wrexham rather than Premier League sides.
In a recent interview with Premier League Productions, he said he "loved" United and that he had "nothing wrong to say about the club" where he has "no regrets."
In his 21 Premier League appearances this season, Garnacho has found the net just once, which has sparked conversation about whether he is good enough for a Chelsea team fighting for Champions League football.
His actions come in the same month that Enzo Fernandez flirted with a summer move to Real Madrid, as problems in West London continue to grow for Rosenior, who can’t seem to control his misbehaving squad.
Chelsea face United this weekend as they try to keep up with Liverpool in the race for Champions League football. Garnacho, who was unlikely to start the game before his actions, will almost certainly not be first on the team sheet for Rosenior.
