Declan Rice said Arsenal will need a "magic moment" to reach their first Champions League final in 19 years.
The Gunners faced Paris Saint-Germain in the French capital on Wednesday night, aiming to overturn a 1-0 first-leg deficit as Ousmane Dembele's fourth-minute goal gave Luis Enrique an edge.
Only two teams - Ajax in 1995-96 and Tottenham in 2018-19, lost their first leg in the domestic Champions League semi-finals and continued to reach the finals.
Rice has played a key role in reaching this stage of the game at Arsenal since 2009, as his two amazing free kicks beat Real Madrid 5-1 in the quarterfinals.
"I think the manager calls them magical moments," Rice said.
"But tomorrow night, a semi-final will allow others to maybe get that magic moment. Hopefully again it's me, but you'll need a magic moment to win a game, and as a team we'll need it.
“The way between them is really, really smart. But once we figured out how to beat them, we missed a few opportunities, but as far as we drove with the ball, we gave our winger a V-on-one opportunity, the opportunity started to open up.
"I think we need to do the same thing tomorrow night. We need big balls, we need to go there on the biggest stage, showing that we are ready to play at this level."
Former Manchester United forward Wayne Rooney claimed after last week's first leg that Arsenal had a "psychological fear" about winning the trophy after winning the only FA Cup in the five-year head of Mikel Arteta.
Rooney, who won the Champions League with United in 2008, said: "We have seen Manchester City finish several times in the league several times, they are already close to Liverpool, and now they beat Madrid, there is a hurdle they have to overcome."
But Rice mentioned in the group stage that he beat PSG 2-0 on October and said: "It's the same team except Dembele and (Khvicha) Kvaratskhelia. Everyone else started and we beat them."
"So there is no fear. I think the goal within four minutes might have shocked us a little, shocked the atmosphere.
“But once we found a foothold in the game again, we started creating opportunities. The goalkeeper (Gianluigi Donnarumma) made some amazing savings. We totally believe we could beat them.
"Obviously, it's not about being, but we've seen enough that we know we can do something very, very good tomorrow night and we absolutely believe we belong to that level."
Arteta urged Arsenal to get inspiration in Madrid's quarterfinals when they beat Real 2-1 in Santiago Bernabeu.
"We're against very difficult opponents in a very convincing way," Arteta said. "The last one is recent, and it's Madrid's violation of all odds because obviously they're talking about all the comebacks, history and what they're doing, and we're proving something very different from what they expected, and we want to do the same tomorrow.
"We are far from the Champions League finals a victory. In the most beautiful city in the world, against great opponents, it's not better than that."
