The 24-year-old endured another tough night at Leicester City on Monday.
Every struggling team needs their supporters to back them but the Chelsea faithful can be forgiven for expressing frustration when their Premier League winning side has now lost nine times in 16 league games.
A reluctance to adapt from Jose Mourinho is certainly a problem, although the Blues boss doesn't have *too* many other options to turn to in terms of his squad.
Faults from players themselves are another big problem. And some Chelsea stars just aren't producing full stop. A case in point is Oscar. What has the Brazilian done this season and what did he do against Leicester?
According to legions of fans on Twitter, the 24-year-old was anonymous at the King Power Stadium - and many want the playmaker to leave Chelsea in January.
In truth, Oscar was anonymous. Supporters were quick to notice it on social media and pundits were quick to criticise on TV, Radio and in print.
It's not easy being a professional footballer. But, when you've won the league title and play like Oscar currently is, there is naturally going to be heavy, heavy criticism...
If Oscar can play week in week out in this Chelsea team, I see no reason why RLC or myself for that matter can't get into the team. #CFC— Cj Harbor (@Mr_Happen) December 15, 2015
Come on then who from the Oscar loving fan base gonna have a debate in what he offers to the team #cfc— kevin pink (@pinksterCFC) December 15, 2015
