David Luiz is delighted to have enjoyed such success in his first full season at Stamford Bridge, and has challenged his Chelsea team-mates to become more consistent next term and compete for the Premier League title.
The 25-year-old Brazilian believes criticism for the club's sixth placed finish in 2011-12 is unwarranted, particularly when you consider the Blues ended the campaign with two major trophies after winning the FA Cup and the Champions League.
"Our titles have silenced many mouths because people had buried us and had no confidence in our results," the defender told The People.
"Nobody gave us the titles we have won - all our rivals fought 100 per cent. I do not accept that Chelsea was a team with luck because it is not true.
"Chelsea are obliged to fight for the Premier League title in the next campaign. This is our challenge and obligation."
After delivering Chelsea's first major European crown in Munich earlier this month, interim manager Roberto Di Matteo has put himself in contention for the full-time post, since succeeding Andre Villas-Boas at the helm in early March.
Luiz admits that he and the rest of the players would love to see Di Matteo handed the role permanently, so great has his impact been, but also paid tribute to the influence of the club's former tactician.
"I insist that AVB is not a bad coach," added the South American stopper. "He has played a part in the success of winning our titles.
"The players have worked very united with Di Matteo, though.
"He demanded us to fight more, show total discipline in our tactics and make much sacrifice. We want Di Matteo to continue, but the decision is in the hands of the owner."
