Lucas Piazon believes some of his Chelsea teammates are lacking the desire to be the best.
"It seems that some people are missing a few things, principally the desire to be champions," Piazon told www.esporte.uol.com.br.
"I think Ramires and David Luiz, the Brazilians, were the ones who strove to give their utmost, and are therefore the ones who are most upset.
"We lacked character and a love for the shirt. Nobody wanted the ball. At least Oscar tried.
"I won't be more specific but I can say that the team lacked willing. You don't go into a final without the desire to play the ball, that's unacceptable."
