Vladimir Petkovic is seeking to rebuild the confidence of his Lazio players.

The Romans have lost to Siena, Torino and Galatasaray in recent weeks without scoring a single goal.

"I am sure that once we break through, we will start to score without problems," Petkovic told La Gazzetta dello Sport.

"We need to have more belief when in front of the goal and players must take more responsibility in the opposition box."
