AC Milan vice-president Adriano Galliani admitted frustration with Robinho after their 1-1 draw with Champions League opponents Barcelona.
Robinho gave Milan the lead, but fluffed a chance to win the game in the second-half.
"It was an extraordinary chance to take the lead and I won't sleep tonight, as I keep wondering whether he missed the ball or had left it because he thought Kaka was behind him," said Galliani.
"The goal we conceded was exactly like the one we let in against Juventus, with a mistake passing our way out from defence."
