Lothar Matthäus Urges Borussia Dortmund to Strengthen Defense During Winter Transfer Window

The football expert highlights Dortmund's defensive vulnerabilities and advises swift action ahead of the Bundesliga's second half.

Lothar Matthäus, in his Sky column, emphasized Borussia Dortmund's need to bolster their defense, describing it as 'thinly staffed' since the start of the season.
Dortmund currently has only three central defenders—Nico Schlotterbeck, Niklas Süle, and Waldemar Anton—following Mats Hummels' move to AS Roma.
Matthäus noted that makeshift defensive solutions like Emre Can or Ramy Bensebaini are not sustainable long-term, particularly with limited options at full-back as well.
The expert sees no urgent need for offensive reinforcements, even if forward Donyell Malen, reportedly linked to Aston Villa, departs in the winter window.
Matthäus believes Dortmund's strong attacking lineup can absorb Malen's potential exit without requiring immediate replacements.
