Valencia defender Aymen Abdennour is set to leave in January.
The stopper, reports Onda Cero, is a top target for Werder Bremen and talks are already underway.
Abdennour's exit will leave Los Che coach Cesare Prandelli with yet another headache.
It will leave Valencia with only three central defenders: Aderllan Santos, Eliaquim Mangala and Ezequiel Garay. And there is also talk of Manchester City recalling Mangala in January.
