Lucas Piazon has laid into his Chelsea teammates following the club's narrow defeat in the final of the World Club Cup on Sunday.
The teenage Brazilian, who remained on the bench for the entire match against Corinthians in Japan, felt a number of Blues' players showed 'a lack of fight' during the match.
The South American side won 1-0 and Piazon - whose only two appearances for Chelsea have come in the Capital One Cup - told Brazilian website UOL Esporte: "A lot of us were missing the desire to be champion.
"I think Ramires and David Luiz, the Brazilians, were the ones who gave the most, and now they are sad.
"We lacked character. Nobody wanted to fight. We went into a final without the will to win, and that's unacceptable.
"David was upset. I'm not surprised. He was one of the few who cared and gave what he had in the match."
Piazon, however, later backtracked slightly on these comments via Twitter, saying: "Corinthians had more courage to play the final than us, they wanted more this title and they played with more passion than us.
"I would never say something about my team-mates, I'm just 18 and with them I learn a lot of good things."
A victory for Chelsea would have made them only the second British club to win FIFA's World Team Cup.
