Roberto Mancini is demanding more from his forwards after they struggled to threaten in Italy's 1-0 Nations League defeat to Portugal on Monday.
Mancini started with two out-and-out strikers in Lisbon, but neither Simone Zaza nor Ciro Immobile made much of an impact as Portugal dominated.
Portugal scored the only goal of the game through Andre Silva early in the second half, with the 1-0 win the least Fernando Santos' men deserved.
The result leaves Italy with a single point from two Nations League games, and Mancini accepts their problem lies in attack.
"Unfortunately, we are making errors and need to try to reduce them," Mancini told Rai Sport after the game.
