Chelsea defender David Luiz has refused to confirm he will be at Stamford Bridge next season.

The Brazilian has been an integral part of the Blues ever since joining them in a €25m deal from Benfica in early 2011. However, the 26-year-old has been heavily linked with a summer move away from the west London outfit of late, with Barcelona reportedly hot on his heels.

Both Luiz or Chelsea were yet to respond to the speculation about his future and the player has now stated that he does not want to discuss the matter. Napoli are also understood to be interested in the defender.

"I really don't want to talk about my future. At the moment I am only thinking about the national team," the defender stressed.

When asked if he was looking forward to working with new Chelsea manager Jose Mourinho, Luiz said: "I don't want to answer that question."

Luiz made 57 appearances for Chelsea in all competitions last season, scoring seven goals. The centre-back was part of the Brazil squad that played out a 2-2 draw with England in Rio de Janeiro on Sunday.

Luiz joined his compatriot and Barcelona forward Neymar in critisicing the Three Lions for their inability to win any trophies for years, despite possessing a squad full of talented and experienced players.

"I have come into a national team which is used to winning things. England do not win titles. The mentality of winning a tournament is not there and that is difficult. The problem is they do not win anything. I have watched them in previous tournaments and things have not always gone well for them," the Chelsea star pointed out.

"Neymar said some things, but he has been playing in Brazil and is now going to Barcelona. I'm not sure Neymar actually knows much about English football or whether he knows any of the players. Why should he? His comments don't surprise me," Luiz added.
