Paris Saint-Germain defender David Luiz says he has finally recovered from Brazil's World Cup disaster.
Luiz was pilloried for his performance in the 7-1 semi-final mauling at the hands of eventual champions Germany.
The former Chelsea defender, who was speaking for the first time as a PSG player after his record-breaking move, said he has had "time to digest" the shocking performance.
"If the World Cup had finished at the quarter-final stage then you wouldn't be asking questions about my ability," the 27-year-old said at a press conference.
"I've had time to digest the end of our World Cup and now I'm ready to do everything to help PSG."

1/22 Brazil: Julio Cesar
Having performed so well before, especially in the last 16 against Chile, must have been distraught at the disaster in front of him. Powerless. 4/10
A 32-year-old with that much experience should be taking responsibility, but Maicon never did, simply making the runs he wanted to make. 3
3/22 David Luiz
Instead of showing discipline and leadership, rising to the role of captain, he was abysmal, playing only his own game and abdicating all responsibility. 2
Always unlikely to replace Thiago Silva adequately, and he provided none of the skill, awareness, leadership or discipline his captain does. 3
Conceded the corner for the first goal and never looked especially keen on stopping Germany from adding to their tally. 2
6/22 Luis Gustavo
Asked to provide balance in midfield, he was swamped by Khedira and Kroos, as the spine of this Brazil side melted away in the first half. 3
Utterly outclassed by the German midfield, he could barely get on the ball until scoring his sharp consolation goal. 4
Just as anonymous as he had been for the rest of the tournament and once the damage had been done he was booed and jeered by the fans. 2
Meant to provide energy and presence in midfield but he was dismal, swamped by German numbers and gifting the ball for the fourth. Off at half-time. 2
Did have an opening or two in Brazil’s bright opening but, not for the first time, lacked the skill to take advantage. Did not make the second half. 2
Trusted to fill Neymar’s role, by the time he saw the ball Brazil had already lost. At least he wanted to try things in the second half. 4
12/22 Germany: Manuel Neuer
Did in fact have a few saves to make, early in the second half, and he was impeccable again until Oscar’s late consolation goal. 7/10
Made one excellent tackle on Marcelo when the game was still 0-0. After that it was all attack, crossing well from the right for the third and sixth goals. 8
Called upon once or twice to defend, which he did very well, and spent the rest of the evening admiring the quality of his team’s forward play. 7
His only disappointment, having come off at half-time for Per Mertesacker, is that he could not add to his goal tally for the tournament. 7
Not quite as incisive as Lahm on the opposite side, but was still impressive, never once beaten defensively and providing a useful option out wide. 7
Operating in the oceans of space in front of Brazil’s centre-backs, he played the through pass for the second goal and scored the third and fourth. 10
Can barely have expected such a comfortable evening, winning the ball and moving it forward for his team-mates to do the damage. 8
Showed he is one of the best big-game players in the world, with that brilliant nose for goal to score the first. Wonderful movement from then on. 10
The man whose expert shuttling and well-timed runs destroyed Brazil’s collapsing system. Made the fourth, scored the fifth and could have had more. 10
Had more than enough space in wide areas to enjoy himself, always moving intelligently and involved in creating two of the first-half goals. 8
On the night Germany humiliated Brazil, Klose broke Ronaldo’s World Cup scoring record, beating Julio Cesar for the second goal. 8
The £48m fee makes Luiz the most expensive defender ever, and Luiz says he can't wait to get started in Ligue 1.
"I feel privileged," he added. "I'm part of a fantastic team in which everyone has something to teach me. It's wonderful to be part of this project," he said, while adding that "Chelsea are history".
"I hope to be 100% next week and on the pitch as soon as possible. I'm ready to help in any position on the field."
Luiz won an FA Cup, the Champions League and the Europa League with Chelsea, scoring 12 goals in 143 matches.
"David Luiz will help us achieve our goal of winning the Champions League," said PSG president Nasser Al-Khelaifi.
The Qatari also said that the club will not be signing Real Madrid and Argentina winger Angel Di Maria.
"It is true that we have held talk with Real Madrid president Florentino Perez but he is too expensive for us. We have stopped negotiations."
