'All-or-nothing' clash with Bayern will define Real Madrid's season, insists Bellingham
Without any trophies in the previous campaign, Real Madrid faces the prospect of another trophyless year, though the Champions League might offer their strongest opportunity this time around.
Bayern Munich leads 2-1 following their victory in Madrid and simply requires a non-loss to advance to the semi-finals.
Addressing the media in Munich on Tuesday, Bellingham declared that Real Madrid's campaign would essentially conclude if they cannot move forward on Wednesday.
"Considering what's happened in the league, in the cups, it's almost a final for us tomorrow," the England midfielder stated.
"Given the situation we're in, we want to be still playing for something, rather than having games pass us by."
Real Madrid trails their fiercest competitors Barcelona by nine points in La Liga with nine matches remaining, after suffering defeat in the Spanish Super Cup final against them. Additionally, Real Madrid exited the Copa del Rey in the round of 16 against second-division side Albacete.
"Any loss in the Champions League feels like a disaster, and like I said, given the situation we're in, we understand tomorrow is a final," said Bellingham.
"It feels as if everything's riding on this game. We have to see it like that. It's an all-or-nothing game.
"We'd like to believe that we'd have more chances if it doesn't go well tomorrow, but that's not how football is.
"We've dropped too many points in the league. Tomorrow, we've got a chance to remove all of that. If we do well in the Champions League, then the league can take a backseat."
The 22-year-old commended England captain Harry Kane yet affirmed he would exert every effort to prevent the Bayern forward from triumphing.
"Hopefully, we can stop him from winning the Champions League tomorrow, which will have a big effect," he said.
"He's a sensational player. He's reached a level where he's almost perfected his craft. It's a joy to watch as a teammate."
Bellingham shone after substituting in the first leg as he progresses his recovery from a hamstring problem.
"It's been a bit of a frustrating season for me," he said.
"But I'm feeling good now. The most difficult thing about coming back is mental. A scan can tell you a hamstring is fine, but a lot of the block is in your head."
The midfielder refuted speculation that he was indulging excessively in life in the Spanish capital.
"People were making things up about my private life, that I was in the clubs, like to drink, that I was out often. It's simply not true," Bellingham emphasised.
"I've enjoyed nights out in Madrid, of course I have, but how often they said I was going out just didn't happen.
"I'm very professional. I'm at the training ground every day trying to better myself in a lot of ways."
Real Madrid's coach Alvaro Arbeloa expressed confidence before the fixture, noting that his squad would draw on their storied European success.
"We are Real Madrid, a team who come here thinking about winning. We are the team of 15 Champions League titles, a team of great players," he remarked.
"Nobody knows how it'll end, but what we're sure of is we're Real Madrid, and with our weapons we can try everything.
"We simply need to show who we are."
