Germany opened their World Cup warm-up campaign with a commanding 4-0 victory over Finland, though the result was overshadowed by concerns over the fitness of forward Deniz Undav.

The convincing win gives Germany momentum heading into their next preparatory fixture — a highly anticipated clash against the United States — but the potential absence of Undav could cast a shadow over their preparations.

Undav's condition will be closely monitored in the coming days as the coaching staff assesses whether he will be available for selection ahead of the meeting with the United States.
