Roma coach Rudi Garcia says the offensive players should have defended better after his side's 2-1 defeat away at Milan.
Roma continue to lead the fascinating battle for a top-three finish in Italy but Lazio and Napoli will be eager to close the distance when they face Internazionale and Parma respectively.
"We did well in the first 10 minutes of the game, hitting the post and creating chances," Garcia told Sky Sport Italy.
"But we then struggled and failed to control the game.
"In the last 25 minutes of the game we played better and created more goal-scoring opportunities.
"We allowed Milan to attack us on the wings and maybe this means that our strikers failed to do their defensive duties properly.
"[Mattia Destro's goal?] No, it's not a problem, it's bizarre that a player on loan scores against his own team, I'm happy for him and disappointed for us.
"The problem is not that he scored but that Milan did after our midfielders gave the ball away cheaply. We allowed them to cross and there's only ourselves to blame."
