Borussia Dortmund's Defensive Overhaul: Ait Boudlal and Future Plans
Borussia Dortmund are bracing for a summer of upheaval at the back – and they don’t intend to be caught staring at the exit door.
Inside Signal Iduna Park, the message is clear: plan now, or pay later. With uncertainty swirling around key centre-backs, BVB have moved early, identifying Rennes defender Abdelhamid Ait Boudlal as a priority target, according to Sky.
A new pillar for a new back line?
At 19, Ait Boudlal is hardly a household name in Germany, but his reputation in France is accelerating fast. Under contract at Rennes until 2028, he is already viewed as one of the standout defensive prospects in Ligue 1 – the sort of profile that usually attracts a queue of elite clubs and an ever-rising price tag.
Dortmund want to get there before the rush.
The teenager’s stock rose further this year when he ended up an Africa Cup of Nations winner with Morocco, in a campaign shaped as much by legal rulings as football itself. He barely featured on the pitch – just a brief senior appearance so far – yet his inclusion in that squad underlines how highly he is rated within a fiercely competitive national setup.
For sporting director Ole Book, Ait Boudlal represents more than a talent grab. He represents a potential cornerstone for the next defensive era.
Schlotterbeck saga forces Dortmund’s hand
The urgency stems from one name: Nico Schlotterbeck.
The Germany international has become a fixture in the Dortmund XI, a left-footed centre-back with presence, personality and a clear bond with the crowd. But contract talks have dragged on, and dragged publicly. Each week without a breakthrough cranks up the tension a little more.
Sections of the fanbase have grown weary of the stalemate, frustrated by the drip-feed of updates without resolution. Inside the club, the leadership knows the danger of drifting. Allow a situation like this to fester and you risk losing both a key player and the initiative in the market.
So Dortmund are moving as if Schlotterbeck might go.
They would prefer to keep him. That much is obvious. Yet the reality of the modern game is unforgiving: sentiment doesn’t secure back lines, and loyalty rarely survives an attractive offer elsewhere. If Schlotterbeck opts for a new challenge, the pressure on the recruitment department will be intense. They cannot afford to be reactive in August.
Ait Boudlal is their attempt to get ahead of that storm.
Sule exit deepens the defensive hole
As if the Schlotterbeck situation were not complicated enough, Dortmund are also preparing for life without Niklas Sule.
The former Bayern Munich defender is widely expected to move on in the summer window. His departure would rip a chunk of experience and physical presence out of the squad – the sort of attributes that are hard to replace with a single signing, let alone a 19-year-old still learning the game at the top level.
Lose Sule and potentially Schlotterbeck in one window, and you don’t just tweak a defence. You rebuild it.
That is the scenario Ole Book must plan for. One new centre-back will not be enough. Dortmund are already casting the net wider, with names like Marcos Senesi and Joane Gadou repeatedly surfacing as options under consideration. The scouting department is working across Europe, piecing together a shortlist that can withstand the brutal realities of the transfer market: bidding wars, late hijacks, and players changing their minds.
Right now, Ait Boudlal is the name with the most traction. He may end up the first piece, not the only one.
A wider reset: from back line to byline
The overhaul will not stop at central defence. Inside the club, there is a growing desire to reshape the attack as well, shifting back towards a more traditional winger-driven system – wide players hugging the touchline, stretching the pitch, providing the kind of chalk-on-the-boots threat Dortmund fans associate with some of the club’s most exhilarating sides.
The current squad, though talented, is not seen as perfectly built for that blueprint. Too many forwards prefer drifting inside; not enough live on the flank and attack full-backs one-on-one.
That is where Diego Moreira comes in. The Strasbourg winger, tied down until 2029, has emerged as a serious option. Young, dynamic, and hungry for the next step in his career, he ticks many of the boxes Dortmund are looking for in a wide player who can both develop and deliver.
If Ait Boudlal is the potential anchor of a new defence, Moreira represents the spark for a refreshed attack.
A crossroads summer
All of this points to a pivotal summer at Signal Iduna Park. A club that has too often reacted to departures is trying to flip the script, to build before the cracks appear rather than plaster over them when it’s too late.
Whether Schlotterbeck stays or goes, whether Sule’s exit opens an even bigger gap than anticipated, Dortmund’s intent is unmistakable: they want to emerge from this window younger, sharper, and structurally stronger.
The question now is not whether change is coming, but how bold BVB are prepared to be when the first big decision lands on Ole Book’s desk.
