Barreto scored the winner for Bari in the important 2-1 win.
“It wasn’t an easy game, but the important thing was to give everything and collect the win,” he told Sky Sports after the game.
“It is a success that is worth a lot to us, we needed it for our morale.”
Barreto scored his goal from the penalty spot after being brought down in the area.
He added: “I did not look to [coach Giampiero] Ventura? Until I can’t do it any longer, I will kick from the spot. When the job is assigned to another I will accept these decisions as I have always done.”
