Roma coach Rudi Garcia has admitted that his side need to start scoring more goals if they are to improve.
The Giallorossi were again very disappointing at home as they registered another goalless draw at the Stadio Olimpico.
And the Frenchman calls the draw with Parma a "disappointing" result as Roma's title hopes are dealt yet another blow.
"We were slow in the first half," Garcia told Sky Sport Italy.
"We know we have to score first when we play against teams that defend. We improved in the second half but we failed to score and when you don't score everything becomes more difficult.
"If we play the way we did in the second half then victories will come but we have to start scoring when presented with the opportunity to do so.
"The fans [who booed] want to win, it's normal. We are all disappointed especially because we drew against the last in the table. We will now do our best to get back on winning terms on Thursday.
"But credit to Parma, they never gave up."
