Oscar not seeking Chelsea departure
Mourinho has substituted Oscar in 18 of the 24 Premier League matches he has started in the current campaign and is said to be unimpressed with the midfielder's work-rate.
Juventus and Liverpool have been linked with a move for the Brazil international, but the 23-year-old is eager to remain at Stamford Bridge.
He told Perform: "I'm very happy here. I get along with everyone here and the club shows its praise to me.
"Chelsea is one of the best clubs in the world so I can't see why I would think of leaving the club."
Former Internacional man Oscar is pleased with the impact he has made for the Premier League leaders this season, but stressed that there is still room for improvement.
He added: "I'm very happy with Chelsea's season so far. I'm happy with my own performances as well but reckon that I could have contributed more to the team.
"There are different tactics depending on the opponent we face and we respect the manager choices. Sometime I ended up not playing the entire match but I'm doing my best to fulfil my role.
"So yes, I'm happy with my performances."
Chelsea are seven points clear at the top of the table ahead of Saturday's clash with Manchester United at Stamford Bridge.
