David Luiz: 'I'm happy working under Jose Mourinho'

Chelsea defender David Luiz has insisted that he is happy working under Jose Mourinho as reports continue to link him with a move away from Stamford Bridge.

The Brazilian, who is believed to be a target for Barcelona and Paris Saint-Germain, claims that he is still eager to improve his game with Mourinho's help.

"He has a great ability to work," Luiz told reporters.

"I'm a guy with an open heart. I want to learn every day. I'm happy with this, I'm happy when I can play for a big club and have an opportunity to work with a good coach."

Luiz has made 27 appearances for Chelsea under Mourinho this season.
