The long-term importance of the Premier League has got in the way of the club's interest in the competition in recent years, but the young Swede has a hunch it will be different this time.
"Maybe we have not done so well in the competition in the past few years, but I can say the FA Cup is a really big tournament and we want to go far in it and badly want to win on Saturday, for sure," Kacaniklic told the Fulham Chronicle.
"That goes for me personally, but I think the whole team as well. We should be a team that has a chance to go to the end of the competition and it would be great to get to Wembley.
"I think now we also want to carry on winning after beating West Brom. That is important to us because we don't want to slip back. We want to go out and get another win."
