After seeing a young side ease past Carlisle in the third round, the Spurs assistant believes his side can start to think about a day out at Wembley in February.
Andre Villas-Boas' men booked their place in the last 16 with a comprehensive 3-0 win at Carlisle on Wednesday evening, and Freund sees no reason why they cannot go all the way in the competition.
"It is special to go to Wembley and I think the players will start to think about that now," Freund told the Daily Telegraph. "I know eight Premier League sides are already out, and there are only two games and then we are in the semifinal."
Spurs secured their third round victory after making eight changes to the side that beat QPR in the Premier League at the weekend, and Freund believes this is testament to the strength in depth at Villas-Boas' disposal.
The German coach was particularly excited by the performances of some of the younger players brought into the side, as well as some senior players who have been on the fringes of the first team so far this season.
"We brought a few young players in and we believe in them all," Freund continued. "Adam Smith was fantastic at right back and Ryan Mason has been scoring in the development squad, so we knew he can play. Then in the center of midfield Tom Huddlestone is back after his injury, Michael Dawson is back.
"There are young players coming through which is nice to see, and it is especially nice to know that we have someone [Andros Townsend] behind Gareth Bale who can jump in and create something. Don't forget, we have several injured players and still had a fantastic, strong team on the pitch today. We deserved to win in the end and it was difficult for Carlisle to create chances. That's why I'm really happy, as is the whole of the coaching staff."
The only question mark from the evening was the non-involvement of new signing Hugo Lloris, with Carlo Cudicini given a run-out between the sticks and Heurelho Gomes taking a place on the bench.
However, Freund refused to be drawn on when the French international will make the number one jersey his own.
"I think at the moment we are just going from game to game," he said. "It is not the right moment to talk about individual players because we had a fantastic performance as a team today. Let's see tomorrow who is available for [Saturday's league game with] Manchester United."
