Sandro Schwarz says he does not think it is the "biggest surprise" that the New York Red Bulls have reached the MLS Cup final.

They beat Orlando City 1-0 in Florida on Saturday to win the Eastern Conference for the first time in their history, and they are now just one match away from claiming an elusive maiden MLS Cup.

The Red Bulls, who also beat reigning champions Columbus Crew and New York City FC in the playoffs, finished seventh in the regular season and will be the lowest-ever seed to play for the trophy.

Having overturned the odds along the way, Schwarz was delighted to see the team's work had paid off as they reached the MLS Cup final for the first time since 2008.

"Maybe for a lot of people, it's the biggest surprise now that we are in the MLS Cup final," he told reporters. "To be honest, for me, it's a very good feeling. But it's not the biggest surprise.

"It's clear when you win against the champions from last season, Columbus, that you have more confidence in your quality, your performance, and you believe.

"It starts always with the result, but you have to prepare the result very seriously and very professionally.

"Now we are in the MLS Cup final. Now is the day to enjoy. [Sunday], we start to work hard for next weekend."

They will face LA Galaxy, who also triumphed 1-0 in their Conference final, beating the Seattle Sounders at Dignity Health Sports Park.

Dejan Joveljic scored the winner in the 85th minute, netting his 20th goal of the campaign for the Galaxy.

They will be playing in the showpiece for the seventh time and the first since 2014, when they won the last of their five titles.

As the higher seed, the Galaxy will play at home on December 7, and head coach Greg Vanney is excited to have that advantage once more.

"I'm super excited for these guys to be able to lift a trophy [on Saturday], but the objective is still one week away and that's where my emotions are," Vanney explained.

"I stay kind of focused on that because when one game ends, the anxiety for the next game already emerges, right? So that's where I'm at.

"When the guys walk into the stadium for the game to start, and it's full and the crowd is going before the whistle blows… I just feel like this group is right from the whistle with the fans ready to go. All 90 minutes matter, and we saw that [against Seattle].

"We're really appreciative [of the fans] and we want to do it one more time, and we want to get the sixth one for them."
