Roma coach Luis Enrique knows his team's lack of consistency has proved to be their undoing this season.
Roma beat Genoa 1-0 on Monday night for their second straight triumph and climbed to sixth place as a result. Roma are now just four points behind third-place Lazio, who occupy the last Champions League qualifying spot.
He said: "There are 10 games remaining but we still have to face Udinese and Napoli, who are both ahead of us in the table. It's going to be very difficult because Lazio and Udinese have always been ahead of us in the standings this season.
"We have shown signs of improvement. But in a tournament like this, in order to win you need consistency. The standings say we are sixth and we don't deserve to be any higher.''
Roma have won 13 of their 28 league games so far and travel to the San Siro to face Serie A leaders AC Milan on Saturday.
