Newcastle United boss Rafa Benitez is desperate not to lose Jamaal Lascelles.
The Toon defender is being linked with Chelsea.
The Sun says Lascelles' impressive season has alerted the Blues, who want a new centre-half and are also keen to add more English talent to their squad.
The former Nottingham Forest starlet, 24, only penned a new deal at St James' Park in October.
That tied him to the Toon until 2023 and boss Benitez — if he stays this summer — will insist that club chiefs do not cash in on his skipper.
