The Partenopei missed out on a place at the semis after losing to Juve on penalties, following 120 minutes of stalemate in Torino.
“We aren’t very lucky at the moment. It’s a big disappointment to go out. We certainly deserved better but things just didn’t go our way.” Reja said.
Napoli had the chance to win the tie before extra-time, when Marcelo Zalayeta and Ezequiel Lavezzi wasted two golden opportunities.
“We created a lot of chances without ever putting one away. It ended in penalties and with penalties you always need a bit of luck.
“At the moment, we simply don’t have any luck. We played a great game. I am very disappointed. We deserved more.”
Reja’s team will now be left to fight for a UEFA Cup place via Serie A, as they are eighth in the table with 34 points.
