Brazil national team boss Luiz Felipe Scolari has revealed he is not worried about David Luiz's recent omission from Chelsea's starting line-up and has labelled the star 'one of the best in the world'.
The Brazilian international has lost his place in Jose Mourinho's starting line-up due to Luiz's poor performance against Newcastle United.
Gary Cahill has since replaced the 26-year-old and has formed a steady partnership with Chelsea skipper John Terry.
Luiz has been linked with a move away from Chelsea, however Scolari believes the former Benfica star should stay and fight for his place at Stamford Bridge.
Scolari, speaking to Setanta, said on Luiz's current situation: “I have spoken to David about it [his lack of appearances] but I am not worried.
"He is one of the best defenders in the world and Mourinho is an intelligent guy.
“He won’t leave a player like that on the bench all the time. If the worst comes to worst, David will arrive fresh and rested for the World Cup.”
Scolari, who will manage Brazil in next summer's World Cup, has not ruled out the prospect of one day returning to the Premier League.
The 65-year-old managed Chelsea for seven months before being replaced by Guus Hiddink after a string of poor results.
Despite his poor experience in England, Scolari has revealed he would return to the Premier League if he was offered the chance.
“I was upset by the way my departure from Chelsea happened,” he added. “I was being honest with the club in everything I did. We were doing reasonably well on the pitch.
“I wish my work at Chelsea could have lasted longer, especially because I was prepared to spend at least two or three seasons in London and experience the Premier League and Champions League football.
“A few players did not agree with the decisions I had to make for the good of the team. I heard them complaining and saying: ‘I don’t play in this or that position'.
“Never mind the fact that one of the players I had put into the first team was actually one of the league top scorers at that point.
“If I had to return, I would do it.”
