Borriello's effort was parried during the 3-0 defeat to Shakhtar.
"I always designate the penalty taker before a game. Both at Lecce and tonight it was Pizarro, but anyone who plays football knows that at times a player really feels it," explained Montella.
"Pizarro allowed him to step up without a problem. I feel bad for Marco, so next time I'll just take the penalty!"
"Before the game I asked the lads to be consistent and improve aside from the result. In that respect I'm happy, as until we went a man down, we created a great deal and had a good approach towards a fine squad.
"We had five or six shots on goal in the first half, then the red card changed everything. In any case, I have promised not to talk about referees."
