Brasília: Brazilian star Lucas Moura has given himself just six out of ten for this year`s showings with Paris Saint Germain and has vowed to do better in 2014.
"It`s been a learning process this season," the attacking midfielder told broadcaster SporTV as he looked ahead to a year when he hopes to play a role for the hosts at the World Cup.
"I feel secure in the knowledge I grew personally as well as professionally. But I still have to grow and I am sure I shall be more prepared next season.
"If I had to give myself marks out of ten I would say six," added Lucas, who Monday played a charity match at Jundai, 60km from Sao Paulo.
Lucas, 21, arrived at the Parc des Princes in January from Sao Paulo.
But he has only intermittently lived up to his 45 million euros price tag with strikers Zlatan Ibrahimovic and Edinson Cavani stealing much of the PSG limelight.
His inconsistency saw him left off Brazil`s last squad with coach Luiz Felipe Scolari, who will unveil his final squad on May 7, preferring Chelsea`s Willian and Milan veteran Robinho.
And he was only a fleeting presence at last June`s Confederations Cup, with Scolari preferring Hulk and Bernard.
"My dream is to play the World Cup in my home country and make history with the national team. I have to work -- but I`m confident in my potential," he said.
