Juventus want to sign Oscar according to reports in France, where Paris St-Germain are also said to be interested in the Chelsea star.
Le Sport 10 say Juve sent scouts to watch Oscar in the Champions League game against Galatasaray on Tuesday and are considering tabling a bid for him this summer.
The 22-year-old is under contract at Stamford Bridge until 2017 and Chelsea manager Jose Mourinho has said he believes Oscar will be a key player for the Blues in the future.
Manchester City are prepared to spend £30m in order to beat Chelsea to the signing of Southampton star Luke Shaw, according to Goal.com.
Tottenham and Manchester United are also reported to be interested in the 18-year-old left-back, who recently made his England debut.
It is claimed that Chelsea and Spurs have indicated to third parties that they are willing to pay Southampton £25m.
Meanwhile, Rome-based newspaper Il Messaggero has reported that Roma are showing an interest in Fulham’s £12m January signing Kostas Mitroglou.
