Some (translated) extracts:
"During the spectacular high wind landing attempt in Hamburg, it was the young female co-pilot who controlled the plane. The dramatic go around manoeuvre was then carried out by the experienced captain."
They also present this as if it is something that should not have been done:
"It is currently unknown why captain Oliver A. allowed his inexperienced colleague to do the approach during the storm 'Emma'".
