The manager believes the result is a major change in mentality within a squad that has been significantly rebuilt this summer.
“If you're going to win, doing it in the last minute makes it a lot more exciting! What I can categorically say is that wouldn't have happened last year,” he told the media.
“When I came in, I thought we lacked fight, we lacked desire. But we showed that today, and with a lot of new players as well. They showed great character to come back against, make no mistake, a very good side. It's a fantastic result for us.
“I've seen four wins now in the Cup, a lot of good stuff on the ball because we dominated. But today's a different test.
“You've got to deal with the physicality of set plays, which I thought we were excellent at. You've got to deal with people like Braga and Ba-Sy, who are very good players. We've done that really well.
“We showed hunger and that's something I thought the club lacked when I came here. It's only a start. It's a small step in the right direction.”
