The former Barcelona right back has questioned the toughness of the Brazilian after another disappointing showing against Corinthians.
The young Brazilian striker failed to make an impact in the first leg of the State Championship final, with the former Barcelona and Chelsea fullback adding to his growing list of critics.
“Normally he does not play well against Tite, who have a game plan much like in Europe. With two lines of four he is well marked, there is always cover behind the player marking Neymar, this just neutralizes him,” Belletti told SporTV.
“Neymar is broken very easily when he realizes that the game is not for him.
“He has hardly appeared in the game [against Corinthians], he is not feeling confident enough to take on the responsibility that he assumed, and assumed well. This is lacking right now for Santos.”
Belletti did give Neymar the benefit of the doubt, placing some of the blame on the rest of the team.
“He does not have a player that divides that responsibility with him," Belletti said. "Previously you had Ganso, who shared some responsibility of this marking.”
