Sébastien Haller has made a surprisingly quick comeback just months after his second cancer operation.

In the 5: 1 (2: 1) of Borussia Dortmund in the test against Fortuna Düsseldorf in Marbella, the goalscorer of the Bundesliga soccer team, who was diagnosed with a testicular tumor last summer, came on in the 74th minute.

Dortmund's record purchase, committed by Ajax Amsterdam at the beginning of the season for 31.5 million euros, made his debut for BVB on Tuesday.

"It was a great moment for me.

I felt a lot of support.

I tried not to give the coach any alternatives and worked hard for this moment," Haller commented on his brief assignment, clearly moved.

"I get goosebumps that he's back on the pitch.

We were just so happy that he was back," said captain Marco Reus: "We all took our hats off to the fight he fought there.

And how he came back now, with what mental strength - that's strong.

Coach Terzic: "We are proud"

Edin Terzic reacted no less emotionally: "For the first time he wasn't wearing a training shirt, but the jersey of Borussia Dortmund.

We are proud that we were able to be there and experience it today.

It's a great story."

The football teacher longs for further progress: "We hope that he will not show any negative reaction, that we can build on that and increase the workload in the next few days."

This increases hopes that the 28-year-old Ivorian national player will also be in the squad for the first competitive game in the sixth Bundesliga team on January 22 at home against FC Augsburg.

"Yes, everything is possible.

In my mind, there are no limits.

I will do my best to be there on January 22,” the convalescent said on Monday.

Haller, who was scheduled to replace Torgarant Erling Haaland (Manchester City), had to undergo a second operation in November.

But even before the official start of BVB training a week ago, he was working in the weight room with great ambition to build up his form.

The good values ​​in the performance diagnostics paved the way back into the team.

In view of Haller's comeback, the result of the game faded into the background.

Felix Passlack (5th minute), Karim Adeyemi (32nd), Nico Schlotterbeck and Donyell Malen (86th/88th) ensured Dortmund's deserved victory.

Fortuna equalized through Dawid Kownacki (7./foulelfmeter) to make it 1:1 in the meantime.

On January 13, BVB will play a second friendly against FC Basel.

A day later, the Terzic team will return to Germany from the training camp in Andalusia.
