Chelsea have rejected an £18million approach from Juventus for Oscar ahead of the summer window, according to reports from the Express.
The 23-year-old was criticised for his performance on numerous occasions over the course of the previous campaign.
It was believed that the Serie A winners were looking to lure him to Italy with an £18million offer, as they were hoping Blues manager Jose Mourinho was willing to sell him in order to fund moves for other additions.
However, it seems Mourinho is standing firm on his earlier revelations that he will not be selling any of his players in the upcoming transfer market.
With the Premier League winners also keeping a watchful eye on Juventus star Paul Pogba, there was even speculation that the Brazilian international could be used in a swap deal to land the midfielder.
He featured 41 times in all competitions this term, scoring a total of seven goals and providing a further nine assists.
