AC Milan legend Arrigo Sacchi has questioned AS Roma's "organisation".
Sacchi is critical of the way Roma's title challenge has fallen away.
"Roma have unfortunately shown that they have limitations in regard to the organisation of the game.
"They're starting from a good base in that they have good technique, but they don't have great rhythm.
"Aside from individual attributes, they're still too reliant on the performances of a player like [Francesco] Totti, who despite everything, is 38.
"Their defensive organisation is still shaky, and in football the individual shouldn't be the only one who counts, the collective has to do more."
