Marc Rzatkowski could still bask in Champions League glory — just on a different continent.

When he joined the Red Bulls on loan from sister club Red Bull Salzburg in January, the talented midfielder became one of just a handful of MLS players to make the unusual in-season switch from the UEFA Champions League to the Concacaf Champions League.

With the Red Bulls set to face Chivas Guadalajara in the first leg of their first-ever CCL semifinal Wednesday night in Mexico, Rzatkowski still has a chance to win a Champions League, a journey that began back in the summer in Austria when Salzburg started their qualifying matches in the more popular European version.

“From my experience, the Mexican team that we played in our last game against Tijuana, they were very hot-blooded and very aggressive,” Rzatkowski told The Post. “In Europe, it’s a little bit more about tactics. But I enjoy playing here.”

Although it’s an interesting route, Rzatkowski isn’t the first MLS player to appear in both prestigious leagues in the same season. Finnish defender Markus Halsti (Malmo FF to DC United) and LAFC defender Laurent Ciman (Standard Liege to Montreal Impact) both made the jump during the 2014-15 season. Former Galaxy midfielder Stefan Ishikazi left IF Elfsborg in Sweden to join the Galaxy the year before.

Former Galaxy striker Robbie Keane took the same route when he left Tottenham Hotspur in 2011. Keane played in a UEFA Champions League match against FC Twente in December 2010 before starring against Honduran side Motagua the following July.

Rzatkowski said he wasn’t used to flying such vast distances, like from New York to Mexico.

“In Europe, it’s a little bit smaller,” he said.

He also found the CCL’s new knockout round stages make it a “much different game” from Europe’s group play, which he came close to experiencing before Salzburg got knocked out in qualification this past summer.

But during the qualification test, he helped Salzburg blow past Scottish side Hibernians, 6-0 on aggregate, when he and former Red Bulls forward Fredrik Gulbrandsen scored in the 3-0 win on July 19.

Overall, he made three appearances in the tournament before Salzburg bowed out to Rijeka ahead of the group stages; however, he’s brought some of that early magic to the Red Bulls both in MLS and the CCL.

“It’s a different feeling,” Rzatkowski said about joining the Red Bulls in his midseason. “In January and February [in MLS], the season starts and it’s new. I like it because I enjoyed the time in Salzburg, but I think I needed something new. It was good for me that the whole season started new at the beginning here.”

He’s appeared in three league games and notched his first two assists in the Red Bulls’ 4-3 loss to Orlando City on Saturday.

In the CCL, Rzatkowski’s been the spark plug who doesn’t earn the spotlights of Bradley Wright-Phillips or Luis Robles. Against Club Tijuana in the quarterfinal, his relentless energy paid dividends when he scored his first goal in the 3-1 second-leg win.

Coach Jesse Marsch has praised Rzatkowski’s tireless work rate, calling it the “best of any player I’ve ever seen” when it comes to closing space in the midfield. His positional versatility has also stood out as both a defensive midfielder and a winger.

“The system is similar to how it is in Salzburg,” Rzatkowski said about the easy assimilation. “A big reason is the team and the staff behind the team because they welcomed me. I’ve never felt this way before because it was such an amazing team spirit to come into, to see everyone supporting each other — it makes me feel very, very nice to play with this team.”

He’s focused on Wednesday and the rest of the season in New York, but he still keeps his eye on Salzburg, who’ve made a miraculous run in the Europa League since being eliminated from the Champions League.

Salzburg last upset German giants Borussia Dortmund and will face Lazio in the first leg of the quarterfinals on Thursday.

“I’m happy for my old teammates because they are really nice guys and they deserved it,” said Rzatkowski, who appeared in four Europa League matches this year. “I watch the games when I can and I’m wishing them all the best. Hopefully, they can go another round.”
