Newcastle are considering Feyenoord defender David Hancko as a cover option at left-sided centre back.
The 25-year-old played a important role in the Dutch side's Eredivisie title win last season, making 28 league appearances in the campaign.
He has also become a regular for Slovakia, picking up 27 caps since his debut in 2018.
Hancko's career began in his homeland with Zilina, and only joined Feyenoord last summer after spells with Sparta Prague and Fiorentina.
He could now be on the move again, with Santi Aouna reporting that Newcastle have 'shortlisted' the defender.
