Newcastle United are on red alert for Belgium international Jason Denayer.
Denayer’s current contract at Lyon expires at the end of the current season and no new deal has yet been reached, meaning the Ligue 1 club could lose him for nothing in the summer.
The Magpies struggled to sign their two top centre back targets in January but did manage to secure Dan Burn from Brighton, while Kieran Trippier and Matt Targett - the latter on loan - were acquired at both right-back and left-back, respectively.
