Spurs face Chelsea tomorrow.
"It's a great venue, a great pitch and the atmosphere is amazing," Modric told the Spurs website. "I can say that it’s one of the best stadiums I’ve played in.
"This is a big game for us, we want to play in the final. We have already played Chelsea twice in the league and they both finished with draws.
"We just need to take the positives from those games and believe in ourselves and try to win the game. It will be a little bit different this time, cup games are always different to the league, but we believe in our quality and hope that we will reach the final."
