Rangers manager Walter Smith hailed his team's achievement after the match.
Smith told ITV4: "This takes a bit of beating - it's an emotional night. We were fantastic tonight in how we worked and prevented Fiorentina from scoring."
Smith continued: "It's the third lot of penalties we've had this season and we've managed to win them all - it's a magnificent achievement.
"We were hanging on a bit though tonight. Credit Fiorentina, they put us under a great deal of pressure.
"But I can't ask more of the boys - they defended fantastically."
Alexander said: "I'm lost for words, what an achievement. We were under the cosh and defended magnificently, the whole team defended well. I said to Barry (captain, Ferguson) 'If I could make one save' and I managed it. Then they put one over the bar."
Novo added: "I still can't believe it. It was a good performance by the team and it's so exciting for the fans."
