Chelsea fans can rest easy knowing David Luiz is feeling beyond content playing under Maurizio Sarri.

The Brazilian centre-back fell out with former Blues boss Antonio Conte last season and had been rumoured to be looking for an exit from Stamford Bridge.

But speaking on Sunday, Luiz exclaimed his desire to stay and praised the new 'Sarri-ball' philosophy being instilled at the west London club.

"I came back to Chelsea to stay here," Luiz said. "When I took my decision to come back here from Paris it was to win the Premier League and to do something again with Chelsea, so I am very happy here."

"I love this philosophy. We play high, with a lot of possession of the ball, in a technical way. He's trying to help us every single day to quickly learn his philosophy, to do our best for Chelsea. You guys know me - I like to be happy, to enjoy my life.

"We have the best job in the world. He came with this idea as a human being, so I think if you're not happy to do your job it doesn't matter if you're a footballer or not. We have to be happy to do our best. A new philosophy always takes time. But it also depends on us.

"We are dedicated every day and doing things every single day in training, especially in this beginning with these friendly games - we are trying to learn quickly. It depends also on us. It is a physical and tactical challenge in pre-season, every single aspect every day, physical, tactical, technical. Football depends on everything. It is not just tactical, it is not just physical, you have to try every single day.

"Yes, it is a challenge for everybody. It is good to have fantastic players, more than just 11. You have many players that can play in the starting 11, so it is a positive challenge for everybody. We are trying to train really hard every single day, double sessions, to learn quickly. It's not just like that, we're doing that every single day."
