Arsenal risk missing out on Ajax defender Jan Vertonghen.
BILD says Hamburg are preparing a January bid for the Belgium international, who has declared this will be his final season at Ajax.
Vertonghen has declared an ambition to join close friend Thomas Vermaelen at Arsenal.
But Hamburg are set to muddy the waters by making a €10 million offer for Vertonghen in the coming days.
Gunners boss Arsene Wenger admits he could buy a new defender this month - and may bring forward plans to recruit Vertonghen.
