Borussia Dortmund Faces Challenge After Konstantelias Injury

Borussia Dortmund thought it had found its missing spark. Within 24 hours, that spark was gone.

On Saturday evening at Signal Iduna Park, Giannis Konstantelias and Konstantinos Karetsas ripped into Hamburger SV and into the narrative around this new-look BVB. Niko Kovac had promised a “different dimension.” The two Greeks delivered it on cue.

“They are two lads who can bring us a different dimension here, and will do too – they showed that today,” Kovac told Sky after the 2-0 win. It didn’t feel like coach-speak. It felt like relief.

A New Kind of BVB

This was not the plodding, predictable Dortmund that has so often frustrated its own stadium. With Konstantelias and Karetsas between the lines, the football had edge and electricity. Not showboating. Not YouTube tricks. Football with a purpose.

Kovac had flagged it before kick-off. The squad, he said, now had the kind of players “many perhaps also demand: spectacular things.” Against HSV, the idea took shape on the pitch.

Both Konstantelias and Karetsas arrived from smaller European leagues, yet they already look like they belong at the heart of a big club. They can do what Julian Brandt once did for Dortmund – but with an extra gear. Where Brandt glided, these two jab and surge. From a standing start, they explode into space, turning static possession into chaos for defenders. Their game lives in the pockets between midfield and defence, where one sharp touch can flip a match.

Konstantelias Takes Centre Stage

For 45 minutes, HSV simply could not get to grips with them. Every time Dortmund played through the middle, the two Greeks popped up, rotated, and drove attacks forward.

Konstantelias had already hinted at this in the Super Cup defeat to Bayern Munich. His close control at full tilt, the way he slaloms through tight gaps without breaking stride, stood out again. So did his work without the ball. Around the half-hour mark he snapped into a duel, won the ball in midfield, and Signal Iduna Park roared as if he had scored.

The goal came soon after. The “cherry on the cake,” as it was quickly labelled.

Shortly before half-time, Konstantelias made it 2-0 and opened his Bundesliga account. The finish carried a slice of luck – a deflection off a Hamburg defender wrong-footed the keeper – but the idea behind it summed him up. A no-look effort aimed at the near corner, full of confidence and imagination.

“First half, top – that was perfect. We implemented everything we wanted to implement,” defensive leader Waldemar Anton told Sky. His praise was not limited to the back line.

Barely 100 minutes into his Dortmund career, Konstantelias already felt like a future cult hero. You could see it in the way the crowd leaned in every time he got the ball. You could almost map out the coming weeks: more flicks, more goals, more noise.

Then came Sunday.

From Euphoria to Shock

A day after the opener, Dortmund confirmed what many had feared the previous evening: Konstantelias had suffered a cruciate ligament tear on his league debut. Several months out. Season reset before it had even begun for him.

“This news hits us very hard because Giannis has already shown in a very short time why we see him as a great player for Borussia Dortmund,” said sporting managing director Lars Ricken. “For now, however, his focus and ours is on his recovery. Giannis has our full support in that.”

The mood had already darkened on Saturday. Shortly after narrowly missing his second goal, Konstantelias twisted awkwardly in a challenge, went down clutching his knee and knew straight away. He left the pitch in the 54th minute looking devastated.

“We have to talk about something more serious there,” Kovac admitted after the game. “We will have the examination on Sunday. But at least it doesn’t sound good, from what the doctor told me.”

The diagnosis confirmed it: with a cruciate ligament tear, Konstantelias is unlikely to be back before well into spring 2027. For a 26-million-euro signing who had instantly lifted Dortmund’s attacking play, it is a brutal halt.

A Different BVB With – and Without – Him

The contrast between Dortmund with Konstantelias and without him was already visible within the same match. In the second half, HSV improved, no question. Yet BVB also lost a chunk of their fluency and menace the moment their new No. 10 walked off.

The mobility, the constant re-creation of angles, the quick-fire combinations between the lines – much of it disappeared. Dortmund’s dominance faded.

HSV captain Nicolai Remberg summed up the problem his side had faced in that blistering first half. “When Dortmund play from right to left, play into the spaces in between, then first of all you do a lot of chasing and don’t really manage to get into the press. That was our problem,” he told Sky.

That pattern had one main source: Konstantelias, dovetailing with Karetsas.

Greek Duo Light Up Signal Iduna Park

Together, the two Greeks were “brutal,” in Anton’s words. They drifted, swapped zones, and kept the ball moving at speed with almost flawless control. Every touch seemed to drag HSV’s shape a little further out of position.

“The mobility they have, how dangerous they are – that is a huge quality at that age and it is something we need for the future as well. I’m glad we have them with us,” Anton said.

Now Karetsas must do it without his ideal partner.

From Dortmund’s perspective, the key question is obvious: how do you replace a player who had just shown he could transform your entire attacking rhythm?

“I felt incredibly sorry for the lad,” sporting director Ole Book said. “From day one here he has had a terrific presence, also in the dressing room. We all already like him very much.” Book had watched, helpless, as the player he and the club’s hierarchy had pushed so hard to sign hobbled off.

Internal Options – and a Red Card Wildcard

On Saturday, Kovac turned to Marcel Sabitzer. The Austrian brings control and defensive stability, but he is not Konstantelias. The tempo changed. The risk went down. So did the unpredictability.

In pure positional terms, Samuele Inacio is the closest match in the squad. The 18-year-old is seen as a top talent and operates in similar areas. His cameo against HSV, though, was memorable for the wrong reason: a lightning red card and a swift exit. Whether he is ready to shoulder Konstantelias’ responsibility right now is highly doubtful.

Maximilian Beier offers another route. More experienced, more proven at Bundesliga level, he could slot into the central creative role. That would force Kovac to abandon his plan of using the Germany international on the flank, creating a fresh hole out wide.

The clock is ticking.

Transfer Window Tension – and the Sancho Question

With the summer window closing on Tuesday, 1 September, at 8pm, Dortmund’s transfer department suddenly finds itself under pressure it had not expected to face.

Ricken had already hinted, even before the full extent of the injury became public, that the club might have to reconsider its stance. “Depending on how serious the injury actually is, we will shape our further steps accordingly. But one thing is certain: over the next three days we are not planning anything.”

Plans can change quickly when your new playmaker is ruled out for most of the season.

One obvious target is already off the market. Said El Mala, once high on Dortmund’s list before the Konstantelias deal, has extended his contract at 1. FC Cologne and is no longer an option.

That leaves a familiar name hovering over the conversation: Jadon Sancho.

Sancho knows this club, this stadium, this role. Stylistically, he fits the profile. Like Konstantelias and Karetsas, he can create dynamism from a standing start, beat a man in tight spaces, and spark life into a static attack.

Speculation about a third Sancho spell in Dortmund had cooled after the arrivals of the two Greeks. Now it will inevitably resurface. During his previous stay, he produced the best football of his career. Since leaving Manchester United as a free agent, the 26-year-old has yet to find a new club and would cost no transfer fee.

The financial risk is low. The questions are not.

Sancho would have to accept a significant wage cut. Dortmund would have to decide whether the player who dazzled here once can still reach anything like that level after underwhelming loan spells at Chelsea and Aston Villa.

For now, the club is left with a jarring mix of emotions: the thrill of discovering a new star, and the thud of losing him almost immediately. The season has barely begun, and already BVB must answer a harsh, simple question:

Can they keep playing this spectacular, incisive football without the man who just showed them how?
