Suso Santana, the club's Spanish winger, is already anticipating a return to Parkhead after scoring his first Hearts goal there last Sunday.
He is also pleased the team have negotiated an awkward third-round tie against First Division Dunfermline after enduring a woeful cup record in his homeland.
"My team always lost in the first round in Spain, but my luck has already changed this week by winning that game, so maybe that's it changed for good," he said. "In order to win something you've got to beat the best. We've got to look forward to this match now and see what we can do."
"We're not talking about revenge, it's a different game and we'll have to approach it in a different manner. Hopefully, we can get a better result. I don't fear anyone and, while having scored there won't help us win, maybe it is a good omen. We have to try and forget about the last result. The goal they scored in the last seconds of the game has gone now and we'll go there with a clean slate and ready to beat them."
Laszlo believes overcoming Celtic in Glasgow could prove a more straightforward task than confronting lower league opponents again. "Sometimes it is easier to play against a team like Celtic because you do not require extra motivation," he remarked. "Celtic being favourites possibly makes it easier for us, but if you want to win the Cup you have to win every game. We must go there with confidence and try to get to the next round."
