The Brazilian was magnificent against Sunderland yesterday.
Chelsea fans were never going to be fully happy with any of the players after the Sunderland game, well, apart from the ever committed Willian.
The rest of the team though couldn't win and rightly so. They have performed poorly under Jose Mourinho and if they turned up v Sunderland it would have confirmed many a fans suspicion that they were not playing for Jose Mourinho, who was sacked in midweek.
One such player was Oscar.
He has been a ghost this season, seemingly unwilling to get involved in games and playing poorly.
The most frustrating thing about his poor form was of course the fact that Chelsea fans know just how good he can be.
Yesterday, he was back.
He was hungry, desperate to be on the ball throughout the fixture and playing some lovely football throughout.
He was even throwing out the odd showboat as Chelsea let rip against Sunderland at Stamford Bridge in a performance that sent a message to their fans.
Oscar will now hope to continue his form for the rest of the campaign. If he does, along with the improved performances of many others at Chelsea yesterday, then relegation will not be an issue.
Here is how the fans reacted on Twitter to his performance...
Oscar was superb today - I get on him a lot but that was a very good performance by him #CFC— L3ahpar (@l3ahpar) December 19, 2015
Oscar pulling the strings in the first half, the best he's been since the first game of the season. Looks like he's been set free... #CFC— Nick (@OhDennisWise) December 19, 2015
Where has this Oscar been all season? Mercy … #CFC— Whit Thompson (@whit_thompson) December 19, 2015
Oscar was incredible today. So much flair and determination in his display, definitely MOTM. #CFC— Ollie Miller (@olliejoemills) December 19, 2015
