Rodrigo Taddei admits Roma were short of ideas during Saturday's 1-0 defeat to Juventus.
"It is a time in which things are going badly for me, but perhaps the whole team is not performing up to its usual standards," said Brazilian winger Taddei.
"In attack, especially, we have got to do something more, as our opponents know us by now.
"Francesco Totti, Amantino Mancini and myself cannot keep playing like this. We have to improve our performances if we want to win again."
