Chelsea midfielder Oscar has signed a new two-year contract extension to ward off interest from French champions Paris Saint Germain.

Oscar's new deal keeps him in west London until 2019 and comes amid an impressive start to the season which has seen him inspire the Blues' surge to the Premier League summit.

The 23-year-old has scored 27 goals in 126 appearances for Chelsea since joining the club from Internacional in 2012 and is a valuable member of the squad at Stamford Bridge.

"I am so happy because I love playing for Chelsea and living in England," he said. "I have enjoyed playing here for two years, and now I have five more, so I am very happy."

During the summer transfer window Oscar admitted he had been approached by PSG over a move to the Ligue 1 side, but the Brazil international said that he had no intention of leaving west London.

"I had contacts with PSG, that is true, but it did not go any further," he is quoted by L'Equipe. "And next season, I will stay at Chelsea."

After criticising Oscar's performance during the back-end of last season, Jose Mourinho said that after he scored the second of his three league goals this season against Crystal Palace in October that the player is finally fulfilling his potential.

"Oscar, in this moment, is not a number 10," Mourinho explained. "He had an evolution, a mental, tactical evolution that allows him to be a fantastic player. Can he physically improve? Of course. People forget that he is still so young."
